Is Clue Birth Control for you?

Because this is a predictive feature, Clue Birth Control works best for those who have predictable periods. Stay tuned to find out when Clue Birth Control is available in your country.

A mockup of Clue Birth Control

Clue Birth Control works for people who:

1

Are able to track their period, and check the app each day they have sex

2

On high risk days, will use a condom every time they have sex that may result in pregnancy

3

Have cycles that are 20 to 40 days long

4

Have had cycles that varied by 9 days or less over the last 12 cycles

5

Have had at least 3 eligible cycles (4 periods) since pregnancy or stopping hormonal birth control

Clue Birth Control is for people who are 18-45 years old. Clue Birth Control does not protect against sexually transmitted infections (STIs)

A mockup of Clue Birth Control

Clue Birth Control is a software application for contraception for women ages 18 - 45 years old, to monitor their fertility and prevent pregnancy. Clue Birth Control is suitable for women with predictable 20 - 40 day cycles, who have not recently used hormonal birth control.

No contraceptive method is 100% effective. There is still a chance that you could become pregnant, even if you use Clue Birth Control. If you have sex on 'high risk' days, you must use an additional barrier method for protection, preferably condoms.

Track your period start dates in the app as accurately as possible. The accuracy of predicting “high risk” and “low risk” days depends on the accuracy of the information you track.

Using Clue Birth Control will not protect you against any sexually transmitted infections or diseases (also called “STIs” or “STDs”). Only abstinence or condoms protect against STIs/ STDs.

You may have to stop using Clue Birth Control if your cycle length becomes too long, too short, or too variable after starting to use the feature. So you should have alternate contraception planned. The app will notify you if this is the case, letting you know that accurate risk predictions are no longer possible.

If you have one or more cycles of 36-40 days in the last 12 cycles, you may have a higher risk of pregnancy.
