When can I start after being on other contraception?
You can start with the measuring few days after quitting your hormonal contraception (you can use Natural Cycles along with the the IUD/coil). This way, Natural Cycles can detect your first ovulation before your natural menstruation comes back. 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 you can use Natural Cycles Prevent along with the IUD (coil).
You can use Natural Cycles with the IUD (coil), both copper or hormonal, as it does not prevent ovulation from happening. Natural Cycles will therefore still be able to detect ovulation and will be able to show you your fertile days throughout the cycle.
You can start with 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 (coil).
IMPORTANT: Do not measure while still on the hormonal contraception (excluding the coil, as stated above), 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.
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.
After quitting the pill
Complete all 21 active pills, you can skip the 7 non-active pills, and wait 7 days before you start with Natural Cycles. If you get a bleeding after the last "active" pill, fill this in as menstruation in the app.
After quitting the vaginal ring
You can start with Natural Cycles 5 days after removing the ring. If you get a bleeding after the removal of the ring, fill it in as period.
Quitting the depo shot
The depo shot is normally active for 12 weeks. Once the 12 weeks have passed, wait at least a week to start measuring with Natural Cycles.
After the implant
Once you removed the implant wait at least a week before you start measuring with Natural Cycles.
After the patch
Wait one week after you remove the patch before you start measuring.
