It is valuable for the algorithm to have the information that you have been pregnant recently, whether your pregnancy went full term or ended in a miscarriage or abortion.
If you have recently given birth, we advise you to start measuring when you get your first period again - regardless of whether you are breastfeeding or not.
When signing up for Natural Cycles, you can enter if you have been pregnant recently and if you've gotten your period since or not yet.
With 'recent,' we mean within the last 12 months. If you've been pregnant in the last 12 months, answer 'yes' to the question you see in the second picture; otherwise, you should answer no.
If you were using Natural Cycles before your pregnancy and logged it into your account, you can enter that the pregnancy has ended directly into the app.
You do this by going to your Profile and updating your goal (for further assistance on this, you can also look at this article). Natural Cycles will take this information into account while getting to know you and your cycles again and also provide you with relevant information. If your menstrual cycle has not returned, you can still use Natural Cycles to know when your first ovulation has occurred and when you can expect your first period.
