You can start with the measuring the day after quitting your hormonal contraception. Please note that it may take some time for your first ovulation or period to show up again, as irregular cycles are very common after having used hormonal contraception. Below you will see some information regarding quitting a few different methods and what to expect. If you get a bleeding right after quitting your hormonal contraception, fill it in as 'spotting' in the app as it's not the equivalent to your period and the two should not be confused.
Until your first ovulation is detected, expect many red days as a Prevent user, and many pink days as a Plan user.
Please note that if you are still using an IUS or an IUD, you may continue to ovulate and you can use Natural Cycles at the same time in order to detect ovulation and to know when your next period is coming (if applicable). Should you want to remove your IUS or IUD, you can then start measuring the day after you have it removed to have Natural Cycles start to not only detect ovulation and when to expect your next period, but also be able to now track your fertility.
You can start measuring as soon as you have a basal thermometer and an account.
If you want to Plan a pregnancy, you can start with Natural Cycles at any time, before or after removing the IUD.
If you want to wait until your natural menstruation comes back and start with the measuring then, you can do so as well, of course.
IMPORTANT: Do not measure while still using hormonal contraception, as the hormones affect your temperature and cycles. The hormones, in general, work to inhibit ovulation and also affect your body temperature making it impossible to combine with Natural Cycles.
