Paternity Uncertainty: Understanding Potential Fathers & Testing Options

Question
My fiance & i broke up temp & i had unprotected sex with another man. March 3-8 was my period. I had unprotected sex approx everyday of my period multiple times with my fiance & he ejaculates in me every time we have sex. We also had unprotected sex almost everyday give or take after that for the month & after with the same result of him ejaculating in me as well. then we broke up (still sexual and ejaculation inside me) & i slept with the other guy approx 2-3 weeks after my period was over on the 8th of march.& had sex twice & he also ejaculated in me. then i go to the hospital and find i am about 6-7 weeks pregnant the 2-3rd week of april. who is the father? I was still having sex with my fiance all the while that i slept with #2 as well. and if i could remember i believe it was 3rd week. i found out i was preggo on the 13th of april hpt and was told i was approx 6-7 weeks the the week of april 15th.
but even if i had sex with #2 the 2 week after and still having sex with fiance does that make a difference? Is there any possible way that i became preggo on my period? and then it would be my fiance's?

Answer
Hello Nyisha,

Based on your due date, you fell pregnant around the 14th-22nd. I would say it is highly unlikely that man number two is the father of your child, but I can't rule him out entirely. However, I would say that it is a very very slim chance indeed, particularly if you had sex after March 22nd.

I hope that helps,

Laura
