Me and my girlfriend had sex and 2 days and we thought it was inpregnation but it was her period which she is still on 5 days later. But a family friend of her said she was pregnant and she had had 2 periods now I thought periods meant she wasn't though? She's paranoid she is but isn't it unlikely she is on the pill and I didn't cum inside her at all not even near. Her period didn't come early but with being on the pill and her starting to take vitamins could this through it off? I mean periods mean she's not pregnant
