Unsure of paternity

[Livelovelaugh90]

I recently got a positive pregnancy test, I believe my last period started on January 21, my cycle is normally 26 to 28 days long…
I was with guy A on 1-28, & 1-29
I was with guy b late night hours early morning of 2/3-2/4

Any thoughts? Suggestions?? I’m confused and torn…

Guy B is much more likely as it would have been bang on your most likely ovulation time for a typical cycle.
But I suppose there is no telling for sure that you didn't ovulate earlier than normal, so no way to be 100% sure based on dates
