The app is giving the incorrect predictions
If your cycle predictions seem inaccurate, it may be that an atypical cycle is affecting the apps calculations. Experiences like pregnancy, miscarriage, use of emergency contraception, or using hormonal birth control to skip a period can lead to one of your cycles being much longer or shorter than what is typical for you. If you are new to getting your period your cycle may also not be regular.

Nothing in this app is intended (and should be relied upon) as medical advice or to serve as a birth control method or contraception. For personal medical advice, birth control or contraceptive advice, please consult your health care professional.
