My first last period was on May 16, I had unprotected sex with my boy friend then on May 28, 29,30, and in June 4th, June 5th, 6, and then I had sex with an ex on 10 th June after midnight with a condom but it broke and he stopped right away, he said he didn't cum yet. I'm currently pregnant and I know it's the first guy my boy friend but I'm just worried because that horrible mistake I made. I have tried counting my ovulation date using the 28 days & 31 days cycle and it's all ranging from 25th may to 2nd of June. Who do you think could be the possible father of the baby? I have also passed my due date by a week and it's continuing to worry me more plus I told my boyfriend his going to a dad soon
