I regularly had sex with my bf during nov and I had mens during the last days of the month and we broke up. Dec 16 I had sex with another guy and he didn't come out inside me and we did that again on 19. And this month I did not have my period but I just ignore it until April 24, my ultrasound result was 20 weeks 5 days pregnant so I counted and it was ex's. So I told him about it and we became together again not because I'm pregnant it's because he was trying to win me back ever since we broke up. So I had my ultrasound again on may 26 and it was 25 weeks and 4days. I was very sure that the father of my baby is my bf because I searched about the lmp thing. And it stressed me out because I do not know my lmp but I'm sure it was the last days of nov and conceive starts 2 weeks after that and the due date was computed through the first day of my lmp. So now I had an ultrasound w another clinic and the result was different, it should be 38 weeks and 5days but the result was 37 weeks and 3days and the due date was on September 15 instead of 6 because that was I'm expecting. So I'm a little bit confused now if who is the father of my child. Pls help
