Help please

Alyssa • Mommy to Arabella Nova ✨🌙
I lost my baby April 9th and my doctor told me that I would be fertile Myrtle for a few months after that. Well I finally had the courage to have sex. I got a period that lasted two day on April 21st and 22nd . I'm starting to have all the same symptoms when I was pregnant. Can someone help me out please? Is it to soon? Is it possible?
