okay. this is bad. this guy I've been talking to for about 6 months now has a really cute friend. we text for a little bit and we ended up having sex. the condom broke but he said it'd be fine and he put another one on. my periods are always irregular so I don't know if I'm not having my period cuz I'm pregnant or because it's irregular. keep in mind I'm in HS I have no idea what to do and I've been stressing about it alot please help
