I had sex with gf a week before the incident as well. We used a condom and afterwards I tie the condom and "play" with it a bit and verify it wasn't broken. Anyways Monday we had sex and the condom breaks... but 20 minutes after we finish having sex she goes to the bathroom wipes and has like a very light period. Her periods normally are heavy and she wasn't due for her period until saturday. On tuesday about 24 hours after sex she takes Plan B just in case, wenseday her light period stopped. I don't know what to do, could she be pregnant? I'm going to buy a test soon to check.
I highly doubt it.
