Because the condom came off, no. It could easily go either way. If it's the others, and your boyfriend wants to claim the child as their own you can go through the court systems and do that. That's why you need to always consider the people you sleep with, because (as you already know) pregnancy is always a possibility. I wish you good luck in this.
WOW, it's highly likely you are pregnant and they both have the same shot, unfortunately, and the only way to know for sure is DNA testing
thank you. is there any way there is more of a chance that it could be my boyfriends now? i'm being really hopeful because if it's the other person's i do not know what to do because he is unfit in every way to be a father and a drug addict/alcoholic and i would not want him to be around my child as much as i would love for it to have the father it deserves. i hate that i even had sex with him at all it was a careless and stupid mistake. i've been with my boyfriend for almost a year and when we broke up it just so happened i had sex with two different people at the WORST time ever.
It's impossible to tell because sperm can live in a female for up to 7 days under proper conditions and you were with two people within a very short time span. The only thing you can do is wait till the child is born and do DNA testing. You should also inform both that they have the potential to be the father so it's not sprung on them later.
