Don’t know who the father is

Truth be told I learned my lesson! Please just be nice! A lot of my friends are calculating that my child is A baby because he nutted in me. But me and B (dad) was having unprotected sex and pretty unsure if he was cumming inside or not because I would be drunk a lot of the times. I had to lie to B dad because he wanted me to get an abortion and sadly I just couldn’t be truthful to him and speak up for myself and say I want to keep her. B dad doesn’t want to do a dna test so I’ll have to go through A dad..Idk how to feel and just need some advice on is this normal to truly don’t know because people are saying when did you conceive which I know when I got pregnant (took the test and it was positive) but that month I had sex with both men pretty back to back. So as a women you really wouldn’t know right??? Because I don’t know honestly I can hope and pray it’s A baby but sadly idk if B was cumming inside and then precum! Also B dad was tracking my cycle, asking me questions after sex “what happens when a girl is late on her cycle” just weird abnormal stuff I don’t blame him at all! But if it’s b he’s going to be so mad he told me he doesn’t want to be on child support and that I shouldn’t keep the baby
