I had sex with two men 1 week apart. I had sex with the first one on 2/27/21 and he ejaculated inside me. I was having some kind of abdominal pain and my doctor gave me an ultrasound to make sure my ovaries didn't have cysts again which was 3/3/21 i was not pregnant. I had sex unprotected with my ex boyfriend on 3/6/21. He pulled out. My due date is 11/28/21 via ultrasound. I'm unsure who's the father please help. I thought i was sure it is the second guy but now he's making me question my math.
