The intended target population for this product is women of reproductive age. The Natural Cycles app can be used in combination with the Oura Ring, which provides temperature data trends during the night. The app processes the temperature data provided by the Oura Ring to determine the user’s fertility status for the day.

Product Usage Instructions

1. Before using Natural Cycles, read the user manual or instructions provided.
2. For initial setup, log in to the Natural Cycles app and follow the connection flow to set up syncing with the Oura Ring.
3. If transitioning from using Natural Cycles with a thermometer to using Natural Cycles with the Oura Ring, start using the Oura Ring at the beginning of your period.
4. Follow the user manual provided by Oura to measure temperature data trends during the night.
5. In the morning, follow these steps to get your fertility status for the day:
6. Sync your Oura Ring with the Oura App. The reading will be automatically synced with your Natural Cycles app.
7. Open your Natural Cycles app and add any other data such as LH test results or period.
8. Check your updated fertility status for the day in the Natural Cycles app.
9. Note: The temperature values provided by the Oura Ring should not be used to make medical decisions or diagnose fever.
10. If you have a condition that affects nocturnal skin temperature, it is not recommended to use the Oura Ring as an input source for Natural Cycles.
11. Only change your thermometer at the start of a new cycle.
12. Exclude temperature variation data using the “Exclude temperature” function in the app if you experience certain circumstances that may affect your data and make it harder for the algorithm to track your cycle.

Natural Cycles may not be right for you if

• You have a medical condition where pregnancy would be associated with a significant risk to the mother or the fetus. Using Natural Cycles does not guarantee 100% that you will not get pregnant. If pregnancy presents a significant risk, you should talk to your doctor about the best contraceptive option for you.
• You are currently taking hormonal birth control or undergoing hormonal treatment that inhibits ovulation. Natural Cycles will mainly provide red days if you do not ovulate. You can explore the app in Demo Mode until you discontinue your hormonal birth control or treatment.

Warnings

• No method of contraception is 100% effective. Natural Cycles does not guarantee that you cannot get pregnant, it only informs you whether and when you can become pregnant based on the information that you enter into the application.
• Even with using the app perfectly, you can still have an unintended pregnancy. Natural Cycles is 93% effective under typical use, which means that 7 women out of 100 get pregnant during 1 year of use. With using the app perfectly, i.e. if you never have unprotected intercourse on red days, Natural Cycles is 98% effective, which means that 2 women out of 100 get pregnant during 1 year of use.
• On red days, you must either abstain or use protection, such as condoms or another form of barrier protection, to prevent pregnancy. If you have not been using a non-hormonal method of contraception before, make sure to have a method on hand to use during red days.
• Our data show that women transitioning to Natural Cycles from hormonal contraception have a higher risk of becoming pregnant due to generally not yet being accustomed to using other forms of protection, such as a condom or another form of barrier protection.
• If you are discontinuing hormonal contraception, you may first experience a withdrawal bleed, which is much lighter than your true period. You will normally get your true period a few weeks later. Withdrawal bleeding should not be entered as “period”. If you are unsure if you are experiencing withdrawal bleeding or a period, please consult your doctor.
• Natural Cycles does not protect against sexually transmitted infections (STIs). Use a condom to protect against STIs.
• Always check your fertility status for the day. Be aware that fertility predictions for upcoming days are only predictions and may change in the future. If you are unsure of your fertility status and can’t access the app, abstain or use protection in the meantime.
• If you are exploring the demo version of the app, this is for informational or instructional purposes only and does not display real data. Do not use the information displayed in Demo Mode for contraceptive purposes.
• If you have taken the emergency contraceptive pill, you should indicate it in the app. You can then continue measuring as normal and the algorithm will take the additional hormones from the pill into account. Note that the bleeding you may experience a few days after taking emergency contraception is not the same as your regular period and should not be entered into the app. If your period is more than one week late after it would normally start you should take a pregnancy test.

Precautions

• As a contraceptive, Natural Cycles may be less suitable for you if you have irregular menstrual cycles (i.e. cycles with length less than 21 days or greater than 35 days) and/or fluctuating temperatures as predicting fertility is more difficult in these circumstances. Natural Cycles’ effectiveness as a contraceptive is not affected by irregular cycles, but you will experience an increased number of red days, which can reduce your satisfaction with Natural Cycles. This can be the case:
• If you discontinue hormonal contraception . It can take several cycles after discontinuing hormonal contraception before becoming more regular again. You should expect more red days during these cycles and therefore expect to use protection or abstain more frequently.
  • If you have medical conditions that lead to irregular cycles such as polycystic ovary syndrome (PCOS) or thyroid-related conditions .
  • If you experience symptoms of menopause.
• After giving birth, we recommend that you start using NC again when you get your first period back, regardless of whether you are breastfeeding or not. If you wish to start using NC before, you should expect to have only red days until your first ovulation is confirmed. How long it may take to get your first period back can vary significantly from person to person, and it is generally longer for nursing mothers. Please note that you are at risk of becoming pregnant even before your first period comes back, and you should use some form of contraception if you wish to prevent a new pregnancy. If you are fully breastfeeding and you have given birth less than 6 months ago, LAM (Lactational Amenorrhea Method) can serve as an effective method of contraception postpartum.
• When you start using Natural Cycles, it can take some time to get to know your unique cycle, resulting in an increased number of red days during your first 1-3 cycles. This is to ensure that the app is effective from the first day of use, and once Natural Cycles has detected your ovulation you are likely to receive more green days. It is important to note that you can rely on the fertility status indicated by the app from the first day of use.
• Always make sure to update your software app, so that you have the latest version. Natural Cycles recommends that you set your smartphone to update the app automatically.
• To ensure accurate data inputs to Natural Cycles, always use a thermometer or wearable that fulfils the specifications stated in the section ‘Checklist’.
• Always follow the directions in the applicable sections ‘Natural Cycles and Oura Ring’ or ‘Natural Cycles and Thermometer’ in order to increase the accuracy of ovulation detection.

Checklist

To get started with Natural Cycles you will need the following:

A Natural Cycles account
You can access Natural Cycles via your web browser, by visiting www.naturalcycles.com. For access via the app, download the app on your Android, iPhone or iPad on Google Play or the App Store. Follow the registration steps to create your personal account. Make sure the device you use to access Natural Cycles is connected to the internet. Your Natural Cycles account is personal and should not be used by anyone except you.

A thermometer or an Oura Ring
To get started you will need an oral thermometer measuring with 2 decimals and which has an accuracy of +/- 0.10 (C) or +/-0.10 (F). You can check the accuracy of your thermometer in the specifications listed in the thermometer’s instructions for use. You can alternatively use an Oura Ring (Gen2 or Gen3).

Ovulation tests (optional)
Ovulation (LH) tests are urine test strips which detect the surge of luteinizing hormone that occurs 1-2 days before ovulation. It is optional to use LH tests with Natural Cycles, but they can help to increase the accuracy of detecting ovulation and can, therefore, increase the number of green days you will see if you are preventing a pregnancy. Using LH tests will not affect the effectiveness of Natural Cycles as a contraceptive. If you are planning a pregnancy, we recommend using LH tests as they can help to find your most fertile days. You can purchase LH tests at shop.naturalcycles.com or from within the app itself.

Natural Cycles and Thermometer

How to measure
Follow the user manual provided with your basal body temperature thermometer. If the thermometer was provided to you by Natural Cycles we recommend that you follow these steps when measuring your temperature:

1. Place the thermometer in your mouth and under your tongue, as far back as possible, next to the root of your tongue as depicted in the diagrams below.
2. Only press the power button once the thermometer is in your mouth and in place.
3. Try to keep still while measuring, close your mouth to keep any cool air out and breathe through your nose.
4. Wait until it beeps (approx. 30 seconds).
5. Once you have your reading, add the temperature into the app.

You can use the ‘Measuring Training’ and the ‘Measuring Guide’ in the app to check your measuring skills. The thermometer will save your reading, so you can check your reading once again later. To do this press the “on” button once; the saved reading will appear for a few seconds before the temperature resets.

When to measure
Measure your temperature once a day, on as many days as possible, so that the algorithm can quickly get to know your unique cycle. Aim to measure at least 5 days a week. A tip to help you remember is to place your thermometer on top of your phone before going to bed. Measure first thing in the morning when you wake up, before you get up and out of bed. Ideally measure at around the same time every day (within +/- 2 hours).

When to exclude temperatures
Certain circumstances may affect your basal temperature. This can lead to variating temperatures and make it harder for the algorithm to track your cycle. To help our algorithm learn about your cycle and accurately find ovulation, use the “Exclude temperature” function in the app if you:

• Feel hungover
• Slept differently (>2 hours more/less than usual)
• Feel sick

Remember that everyone is different with different routines and, for instance, little sleep might affect you more or less than others. Exclude your temperature only if you feel that something was out of the ordinary for you and you feel differently this morning because of it. Medication can also affect your temperature. If you take regular medication or anti-pyretics (fever reducing substances), it’s worth consulting with your doctor to discover its impact on your basal body temperature.

Changing your thermometer
If you need to replace your thermometer, do this at the start of your period. A basal thermometer is highly accurate, but from one thermometer to another , there can be a small difference in how each one measures. For example, if one thermometer is showing one temperature, the second can show a 0.1°C difference. As the app is looking for the smallest differences in temperatures to be able to locate where you are in your cycle, you should only use one thermometer at a time.Do not change these during the course of a cycle, instead wait until a new cycle has started before changing your thermometer.

Natural Cycles and Oura Ring

How to set up
After logging in to the Natural Cycles app for the first time, you are automatically directed to the connection flow which will help you set up the syncing between Natural Cycles and Oura. If you are transitioning from using Natural Cycles with a thermometer to using Natural Cycles with the Oura Ring, you should start with the Oura Ring at the start of your period.

How to use
Follow the user manual provided by Oura to measure temperature data trends during the night. In the morning, follow these steps to get your fertility status for the day:

1. Sync your Oura Ring with the Oura App. The reading will be automatically synced with your Natural Cycles app as soon as it is automatically uploaded to “Oura on the Web” cloud storagein the Oura Cloud. When the reading has been registered, the Natural Cycles app will indicate the time at which it synced with Oura.
2. Open your Natural Cycles app and add any other data, like LH test results or period.
3. Check your updated fertility status for the day in the Natural Cycles app

Note: Oura Ring provides Natural Cycles with temperature trends which Natural Cycles processes into a single, absolute temperature value used by the Natural Cyclesalgorithm. Do not use these values to make medical decisions (e.g.x: diagnose fever).
Note: If you have a condition that affects nocturnal skin temperature, using an Oura Ring as an input source to Natural Cycles is not recommended.
Note: If you need to change your ring for any reason, you should start using your new ring at the start of your period.

When to exclude temperature variation data
Certain circumstances may affect your data. This can make it harder for the algorithm to track your cycle. To help our algorithm learn about your cycle and accurately find ovulation, use the “Exclude temperature” function in the app if you:

• Feel hungover
• Feel sick

Exclude your temperature variation data only if you feel that something was out of the ordinary for you and you feel differently this morning because of it. Medication can also affect your temperature. If you take regular medication anti-pyretics (fever reducing substances), it’s worth consulting with your doctor to discover its impact on your skin temperature.

Natural Cycles products
Natural Cycles offers three modes for our users to choose from depending on their fertility goal:

• NC° Birth Control – for preventing pregnancy
• NC° Plan Pregnancy – for increasing chances of conception
• NC° Follow Pregnancy – for monitoring the course of a pregnancy

These three modes can be chosen by the user prior to signing up and then within the app, if the user would like to switch between modes.

Contraception: NC° Birth Control

How it works
Your daily morning routine with Natural Cycles is as follows:

1. With thermometer: Measure your temperature when you wake up as described in the ‘Natural Cycles and Thermometer’ section. With Oura Ring: Sync your data when you wake up as described in the ‘Natural Cycles and Oura Ring’ section.
2. Add your temperature (if using a thermometer) and whether you have your period into the app. The view to add data will automatically open, or you can press the ‘+’ icon in the top right-hand corner. You can also add additional data, such as the result of ovulation (LH) test. Once you save today’s data, the app will calculate your status for the day.
3. Check your fertility status for the day – every day. The app will provide your fertility status directly after your first set of data is entered. Your status for the day is displayed in red and green colors throughout the app.

The app will indicate your ovulation as well as when you have entered and are expected to have your period. The application also shows predictions for upcoming days and months. The predictions may change and should not be used as the final result, which is why you should check your status for the day – every day.

Summary of clinical studies – how effective is Natural Cycles for contraception?
Natural Cycles is 93% effective under typical use. Under perfect use, i.e. if you never have unprotected intercourse on red days, Natural Cycles is 98% effective. Clinical studies have been conducted in order to evaluate the effectiveness of Natural Cycles for contraception. The current version of the algorithm (v.3) has been investigated on 15,570 women (on average 29 years old). At the end of the study, the following commonly used failure rates were determined:

1. The app has a method failure rate of 0.6, which is a measurement of how often the app incorrectly displays a green day when the woman is actually fertile and gets pregnant after having unprotected i ntercourse on this green day. This means that 0.6 out of 100 women who use the app for one year get pregnant due to this type of failure.
2. The app has a perfect use Pearl Index of 1, which means that 1 out of 100 women who use the app for one year and who get pregnant will do so either because:
   • a. They had unprotected intercourse on a green day that was falsely attributed as non-fertile (i.e., method failure); or
   • b. They had protected intercourse on a red day, but the chosen method of contraception failed.
3. The app has a typical use Pearl Index of 6.5, which means that in total 6.5 women out of 100 get pregnant during one year of use due to all possible reasons (e.g. falsely attributed green days, having unprotected intercourse on red days, and failure of the contraceptive method used on red days).

Summary of clinical data from 15,570 women on the effectiveness of Natural Cycles of the current algorithm version.

Effectiveness of Natural Cycles for two subgroups – women who used hormonal contraception within 60 days prior to using the app and women who did not use hormonal contraception within 12 months prior to using the app.

You can find an overview of the effectiveness of different contraceptive methods in the Appendix of this manual. This will help you to understand the expected effectiveness of all forms of contraception.

Instructions if you are discontinuing hormonal contraception

If you are discontinuing hormonal contraception you may first experience a withdrawal bleed, which is much lighter than your true period. You will normally get your true period a few weeks later. Withdrawal bleeding should not be entered in the app as “period”.
Note: a copper IUD does not contain hormones and does therefore not inhibit ovulation. You can thus use Natural Cycles alongside a copper IUD to get insights on your body and menstrual cycle without having to use a barrier method on red days.

If you become pregnant on Natural Cycles
If your period is overdue and your temperature does not drop, you may be pregnant and the app will encourage you to take a pregnancy test to confirm the pregnancy. If the test is positive, please talk to your doctor and indicate it in the app.

NC° Plan Pregnancy

When you are planning a pregnancy, select NC° Plan Pregnancy while signing up in the app. If you are already signed into the app, you can go to the settings page and choose NC° Plan Pregnancy . In this mode, your fertility is displayed as a scale, so you can identify the days you are most likely to become pregnant. The same morning routine as in NC° Birth Control mode applies here as well – measure, add data and check your fertility status.

When you’re planning a pregnancy, we recommend taking LH tests since the occurrence of LH coincides with your most fertile days. If your period is overdue and your temperature does not drop, the app will encourage you to take a pregnancy test to confirm the pregnancy.

NC° Follow Pregnancy
Once you are pregnant, the app can be used as a pregnancy calendar and you can follow your weekly development and the development of your baby.

Demo Mode
In Demo Mode you can take a tour of the app. This is for demonstration purposes only, demo mode cannot provide you with any fertility information.
If you are currently on hormonal contraception you will access the app in Demo Mode. Once you stop using hormonal contraception you can then easily access the full version of the app. The app will now function for contraception or for planning a pregnancy.

Problems/ Troubleshooting

If you cannot access the application, the application is malfunctioning, or if you suspect something is wrong with your current fertility status, please follow the steps below:

1. Use protection, such as a condom or another form of barrier protection, until the error has been fixed.
2. Please contact our service desk via help.naturalcycles.com and our trained support agents will assist you.
3. Serious incidents involving this device should be reported both to Natural Cycles and to the competent authority in your country. A ‘serious i ncident’ means any incident that directly or i ndirectly led, might have led or might lead to any of the following:

   • b. the temporary or permanent serious deterioration of a patient’s, user’s or other person’s state of health,
   • c. a serious public health threat;

Application Overview

Your fertility status for the day is shown through different views within the app.

• Calendar tab
  This tab provides the overview of today’s fertility and gives i nsights into the data logged in the past through various views as described below.

• Today view
  On this screen, you will get all of the info you need in one glance. A screen to enter your temperature pops up automatically when you open your app in the morning. Once you’ve entered your data, your fertility status will appear as a colored circle with additional information i nside. Below the circle, you will see the weekly predictions. You can add or update your input data, such as temperature, period, or LH tests, at any time by tapping the ‘ +’ icon.

• Month view
  Tap the “Month” tab in the calendar view to access the monthly view. Here you can see your predicted red and green days for the month, as well as when you are predicted to ovulate and have your period. These may change over time, so you should only rely on the i nformation provided in the “Today” view for contraceptive

• or pregnancy planning purposes. You can easily access your past data by tapping on any past day.

• Graph view
  The graph is a visualization of your temperature curve which will continue to develop as you measure throughout your cycle. Information about ovulation, period, and fertile days is also visible. Swipe from left to right to view your past cycles, and tap ‘3 cycles’ or ‘6 cycles’ to compare them to each other. You can also access the compare mode to compare your period and cycle length, temperature variation and ovulation window and day.

• Top menu
  Under the top menu, you can access and manage all the i nformation regarding your personal profile, the app and privacy settings, and your account including subscriptions. Here you can also manage whether or not you will get reminders about when to use protection, take an LH test, expect PMS, measure your temperature and check your breasts. Note that you must enable Natural Cycles to send you push notifications in your device settings to receive these.

• Offline mode
  When you are offline you can continue to add your temperature and other data to the app. When offline, the app does not calculate your fertility status. Instead, the app will show an orange outlined circle indicating your status as “Use protection”. Use protection (such as condoms or another form of barrier protection) or abstain until you are back online and the app has calculated today’s fertility status.

Using Natural Cycles while still on hormonal birth control

When you use hormonal birth control (such as the Pill, an implant, or a vaginal ring), you don’t ovulate. This means that Natural Cycles won’t be able to track your menstrual cycle.

While you are using hormonal birth control, we recommend you explore the demo version of the app.

Hormonal IUD Implant

Mini-pill Other Patch Pill

Shot/Injection Vaginal ring

Different types of hormonal birth control There are lots of different hormonal birth control methods out there. We’ve included a selection of the most commonly used options. If you can’t see your option on the list, please select “other”.

The pill and the mini-pill

The combined pill is commonly referred to as “the birth control pill” or “the pill”. It contains both synthetic estrogen and progesterone and is typically taken for 3 weeks with a 1-week break. The mini pill (also known as the progestogen-only pill) contains only synthetic progesterone. It’s taken every day without a break. If you are unsure what method you are using, check your pill packet or ask your doctor.

●        Transitioning from hormonal birth control to Natural Cycles

●        In most cases, hormonal birth control stops ovulation, meaning you don’t get a cycle while you’re using this type of method.

●

●        This means that Natural Cycles won’t be able to track your menstrual cycle or show you a fertility status until you’ve stopped taking hormonal birth control.

●

●        Until it’s time to stop using your current method, you can only access Natural Cycles in demo mode. We’ll remind you on the date you set to start measuring.

●

●        Enter demo mode

●        Are you ready to start your hormone-free journey?

●        You must have stopped using your previous method before you can start using NC Birth Control/NC Plan Pregnancy

Have you bled since your shot/injection? Have you bled since you removed your vaginal ring?

You might experience what’s known as a withdrawal bleed when you come off hormonal birth control. This is usually heavier than spotting, but not as heavy as a regular period.

Yes No

●      Getting your period back after the IUD

●      Getting your period back after the implant

●      Getting your period back after the pill

●      Getting your period back after hormonal birth control

●      Getting your period back after the patch

●      Getting your period back after the pill

●      Getting your period back after the shot/injection

●      Getting your period back after the vaginal ring

●      It looks like you’ve experienced a withdrawal bleed and your period has returned. This means you’re on your way to finding your own natural cycle.

●      You’ve experienced a withdrawal bleed and the next bleed you get should be your period. This means you’re on your way to finding your natural cycle.

●      The next bleed you experience is likely to be a withdrawal bleed. After that your period should be next.

●  You can add withdrawal bleeding in the app, it won’t be used by the algorithm in the same way as your period.

Adding bleeding to the app

When you discontinue hormonal birth control, you may first experience a withdrawal bleed, which is much lighter than your true period. You will normally get your true period a few weeks later.

Withdrawal bleeding should not be entered as “period” into the app. If you are unsure if you are experiencing withdrawal bleeding or a period, please consult your doctor.

Using protection on red days

Our data show that women transitioning to Natural Cycles from hormonal birth control have a higher risk of becoming pregnant due to generally not yet being accustomed to using other forms of protection.

On red days, you must either abstain or use protection, such as condoms (or another form of barrier protection), to prevent pregnancy. If you have not been using a non-hormonal based method of birth control before, make sure to have a method on hand to use during red days, such as condoms.

It can take several cycles  after discontinuing hormonal birth control before becoming more regular again. You should expect more red days during these cycles and therefore expect to use protection, such as condoms (or another form of  barrier protection), or abstain more frequently.

●     How many times have you bled?

●     Knowing how many times you’ve bled helps us work out whether or not you’re getting a menstrual cycle.

When did your last period start?

●        I don’t know

How many cycles have you had since you quit hormonal contraception?

A cycle is the time span between one period and the next.

Using Natural Cycles after hormonal contraception

Our data show that women transitioning to Natural Cycles from hormonal contraception have a higher risk of becoming pregnant due to generally not yet being accustomed to using other forms of protection.

On red days, you must either abstain or use protection, such as condoms (or another form of barrier protection), to prevent pregnancy. If you have not been using a non-hormonal based method of birth control before, make sure to have a method on hand to use during red days, such as condoms.

If you have recently been pregnant we can optimise the app to best fit your needs. After pregnancy, your cycle may be irregular and you may not ovulate.

Have you had your period since your pregnancy ended? (not the initial bleeding)

●                 Yes

●                 No

How many cycles have you had since your pregnancy?
When did your pregnancy end?
Have you had your period since your pregnancy ended? (not the initial bleeding)

If you have not had your period since your pregnancy then you haven’t yet started your menstrual cycle. The initial bleeding after your pregnancy is caused by birth and is not a part of your menstrual cycle.

Using Natural Cycles while breastfeeding For the first 4–6 months after giving birth, many women who are exclusively breastfeeding may not ovulate.

Natural Cycles will detect your first ovulation 2 weeks before your first menstruation, but until then you will only see red days in the app.

Even though you are not ovulating, it is still important to use contraception or abstain from intercourse on red days.

Emergency Contraceptives: Use of emergency contraceptive pills or placement of a copper intrauterine contraceptive after unprotected intercourse substantially reduces the risk of pregnancy.
Lactational Amenorrhea Method: LAM is a highly effective, temporary method of contraception.

1. Among typical couples who initiate use of a method (not necessarily for the first time), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any reason other than pregnancy. Estimates of the probability of pregnancy during the first year of typical use for fertility awareness-based methods, withdrawal, the male condom, the pill, and Depo-Provera are taken from the 2006–2010 National Survey of Family Growth (NSFG) corrected for under-reporting of abortion. See the text for the derivation of estimates for the other methods.
2. Among couples who initiate use of a method (not necessarily for the first time) and who use it perfectly (both consistently and correctly), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason. See the text for the derivation of the estimate for each method
3. Among couples attempting to avoid pregnancy, the percentage who continue to use a method for 1 year.
4. This estimate represents the percentage who would become pregnant within 1 year among women now relying on reversible methods of contraception if they abandoned contraception altogether. See text.
5. 150 mg gel, 100 mg gel, 100 mg suppository, 100 mg film.
6. Without spermicides.
7. With spermicidal cream or jelly
8. About 80% of segments of FABM use in the 2006-2010 NSFG were reported as calendar rhythm. Specific FABM methods are too uncommonly used in the U.S. to permit calculation of typical use failure rates for each using NSFG data; rates provided for individual methods are derived from clinical studies. The Ovulation and TwoDay methods are based on evaluation of cervical mucus. The Standard Days method avoids intercourse on cycle days 8 through 19. Natural Cycles is a fertility app that requires user input of basal body temperature (BBT) recordings and dates of menstruation and optional LH urinary test results. The Symptothermal method is a double-check method based on evaluation of cervical mucus to determine the first fertile day and evaluation of cervical mucus and temperature to determine the last fertile day.
9. However, to maintain effective protection against pregnancy, another method of contraception must be used as soon as menstruation resumes, the frequency or duration of breastfeeds is reduced, bottle feeds are introduced, or the baby reaches 6 months of age.
