Is Clue Birth Control for you?
Clue Birth Control works if:
You're 18-45 years old
You have predictable 20-40 day cycles that varied by 9 days or less over your last 12 cycles
You have had 3 eligible cycles (4 periods) since stopping hormonal birth control or removing a copper IUD
You have had 3 eligible cycles (4 periods) since pregnancy
You're able to track your period and check the app before you have sex that may result in pregnancy
You will use a condom every time you have sex that may result in pregnancy on a high risk day
Clue Birth Control does not protect against sexually transmitted infections (STIs)
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.
