Condom Ripped

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.

of course it's possible
it happened to me once (when I was a bit less experienced) and I couldn't sleep the next couple of days from worrying

she took the morning after pill and everything was cool

my problem was that I used too small condom
now I use larger condom and I don't have such problems

if that's also the case with you, you should check some larger condoms
