Birth control and miscarriage

Lindsey • 20. Angel baby 2/18💙 Rainbow 5/19🌈💙

How do I make the app consider various things that made my period stop? I had birth control and didn’t have a period for 2 years. I got off of it last July and got pregnant in December. I had a mmc in February. It’s throwing off my ovulation and cycle averages. Is there any way to change it?
