Really confused, who is the dad?

[Elliebellie28]

My LMP was 20th march and ended on 24th. My cycle ranges from 28-32days.
I had unprotected sex with my partner (guy A) on 25th,26th and 27th. We split up on the 28th.
I met up with an ex (Guy B) and had unprotected sex with him on 2nd April.
I had a positive pregnancy test on 16th April.
I assumed guy B was the father but now I'm really unsure considering the dates I had sex with both men are quite close together. Google is just confusing me even more.
My due date is 25th December. My dating scan on 14th June measured at 12 weeks and 2 days.
Thank you for reading and I really appreciate any help with this.

It sounds like you did conceive around April 2. This most strongly suggests guy B. Unfortunately, sperm can live in your reproductive tract for 4-6 days. This means guy A has an (much less strong) chance. Is the baby a girl or a boy? If a boy, it also suggests guy B, due to a theory called the Shettles method. (Unfortunately Shettles isn't scientific fact, just a theory with adherents.) Can you afford a prenatal DNA test? If so, see if you can test with both guys. If not, do a post-natal test once the baby is here in the flesh, as they are much more affordable.

Thank you for your response.
I do think guy B is most likely to be the father but I think the best thing will be to get a paternity test when baby is born as a prenatal test is unaffordable unfortunately. The baby is a girl, does this give guy A a slightly stronger chance? Thank you.

It doesn't reduce his chances, anyway. Shettles isn't a proven thing.
