Okay, this could be me just being paranoid but I'd rather hear other peoples opinions.
My girlfriend and I had unprotected sex, stupid I know, this was around 4-5 weeks ago now. She took the morning after pill within 24 hours and soon after this she experienced light bleeding, spotting, said she was feeling tired, headaches and the sort. Today she had her period, nothing irregular about it, but I have heard that women can still have their period even when they're pregnant, she's also recently said that she is suffering from stomach cramps and back ache, we haven't had a pregnancy test yet as she is stubborn and says she doesn't need too because she knows she isn't pregnant but like I said I'm paranoid so any answers would be appreciated.
