What are the chances of getting pregnant from precum if a night before when having sex, ejaculation occurred?? My boyfriend and I had sex on april 9th and my estimated ovulation was on the 10th. THis was 4 in the morning and he ejaculated inside me. I was dating someone else and the next night around midnight, things got out of hand and we had sex but we stopped and no ejaculation occurred at all. What are the chances of being pregnant from the 2nd guy when my boyfirend was the only one who ejaculated and it was inside of me and this was before I was with the 2nd guy?
