Paternity question

[MiellaGrace]

Hey so I just wanted a little more insight / opinions. My LMP started March 26. On April 1 ( or it was late so early April 2) I had sex with Guy A, but we used protection. We don’t think it broke but unsure. On April 7 & 10, I had sex with Guy B & we went all the way, no protection & he did not use the pull out method. According to all these app I use to track my cycle and when I have sex, my due date would be Dec 31, but by ultrasound from early on & up until now I’m measuring December 27. I used a few conception calculators & just been asking for opinions.. calculations say I conceived April 5… others says April 7 could also give me a Dec 27 due date . I’m just wondering who is more likely to be dad. My cycle was just going off around March 31 so my first initial complete dry day was April 1. Is my baby just measuring bigger? Who is more possible Dad , Guy a or b

I think your reasons for preferring guy B are valid, but a paternity test would eliminate any doubt.

Either guy is possible, due to the long life of sperm in the woman's reproductive tract and the margins for error in the method you're using. The guy with whom you didn't use protection is more possible than the other guy if the condom didn't fail, but as you tell the story, there is just no "for sure" that can be said. If you have the budget, call the DDC or Ravgen and get a DNA test before the baby is born (test with both men). Or, test when the baby comes for a quite a bit more practical price. But counting back from a due date won't give you the answer you want.

Thanks, it’s just I was more confident in Guy be since it was around my cd 13/14 when we first had sex without pull out method . I also remember having an extremely high sex drive that morning

On April 5, the first guy's sperm would still have been alive in your body, if the condom had failed. By April 7, some or even most of his sperm would have no longer been viable. But it's not known for sure how long sperm can last in a woman's body, so that's why I said neither guy can be ruled out. You need a DNA test to be sure.
