Hi,
My girlfriend went to get the injection as a form of contraception the other night. She was told she should wait a week to have any unprotected sex. A couple of nights later we had had sex and the condom had come off inside her as we had finished - word of advice never use those free condoms, they're pretty small and don't fit so come off easily.

Anyway how unsafe would this be if she had the injection a couple of days before? I told her to go get the morning-after pill just to be sure but she's had it once or twice before and she said the nurses seem to treat you like you've done something wrong and it's fairly embarrassing.
