I don't know who the father of my unborn baby is, I had sex with a guy on January 10th, 2015.. And then on January 31st I had sex with my ex boyfriend. My due date is October 26th, 2015.. And I am now over 37 weeks pregnant. Could anyone help with this? Both guys don't know if they had came in me or not. :/
When did your last period START? Your due date corresponds to an LMP of January 19. In that case the first guy is not the father (you weren't pregnant) and timing wise the 2nd guy (Jan 31) is the father.
That would have been day 12 of your cycle. You'd be near/at your peak fertility.
A DNA test can confirm. Good luck.
