okay so there’s 2 guys in this story. guy 1 (my ex) and guy 2 (somebody i was messing around with) so i had sex with guy 2 twice, both times i was on my period. he used a condom the first time and the 2nd time he took it off half way through but pulled out. well i stopped talking to him and like a week later started talking to guy 1 again and had sex all month with no condom and he didn’t pull out. if i was pregnant would there be any chance that guy 1 isn’t the dad ?
