I didn't have my period but way before it was 7. Days every 28 days, but then I started birth control for a few months probably 6.. anyways my dating ultrasound says I'm due May 8 2020 and I want to know if it's possible that I could have conceived on September 8 2019? I'm so close to my due date and I'm scared the baby will come out to be the other guys (who is in jail now) and not my on and off again spouse, we broke up on September 1st and got back together when I found out I was pregnant again.. I'm absolutely terrified because with our son I got the due dates mixed up, and thought that he wasn't the father but it turns out he was bad the other guy was heartbroken.. I don't wanna make that mistake again.. I'm so stupid :(
