i was having sex with my girlfriend and my condom broke and i didn't notice, when i felt i was cumming i pulled out quickly, but I'm not sure if i penetrated her while i was pulling out, and when i pulled out i just finished around her. Is that possibility of she getting pregnant?
The quick answer is yes, there's a possibility. I've had two occasions where they've broken on me before and I didn't even know until after I came, so I got extremely lucky. But that slight chance does exist.
Its difficult for a lot of women to get pregnant depending on what part of her cycle she's in etc. While it is possible its unlikely... Gotta be careful and talk to your gf about it. She might opt for the 3 day pill if it isn't too late, or check into birth control which could be a win.
