Ok im pregnant. I have used the ovualtion calculators online and my last period was Aug 4. I had an affair on Aug 15th, however, he used a condom during the precum stage, and towards the end, ended up taking it off, and then pulled out completly. During the week of aug 17th to the 22nd, my bf and i had sex daily, and he came in me several times. The ovualtion calculators stated i ovulated on the 18-21st. Do you think the possibility of the other man has a probability of being the father? I feel like it is bf's. But am also wondering about the possibility. I havent been pregnant in 3 years and havent been on birth control.
