Found out im pregnant? had sex with 2fellas 1 on the 28th sep and the other one 3rd and 4th of october,1st boy did not cum in me,2nd boy did. didnt start ovulating untill 30th,egg released on 3rd oct wen i had sex with 2nd fella,is 2nd fella the dad?

Probably: Based upon this info it seems very likely that the 2nd is the father though there is a tiny chance it is the first as sperm can survive up to 5 days and a tiny bit of sperm might have been released by the first. But there is about a 99% chance it was the 2nd. If you decide to have this baby you can do genetic tests after birth to be certain.
