I'm 18 and a freshman in college. I've had protected sex 17 days ago, but there was a moment when I heard a loud snap, assuming the condom broke I checked didn't feel broken and he said it wasn't so, I don't know for certain. Lately I've been waking up in the middle of the night, usually six hours after I fall asleep, with nausea and the need to pee. I've been experiencing cramps, back pain, bloating, fatigue, hunger, sometimes a sharp pain in my vagina and uterus, a milky white discharge that is not mucous like, also my period stopped the day before I had sex so I had started my period probably around Dec. 4th, and my period is also irregular majority of the time. I'm hoping I'm not but all of my symptoms seem to tell me otherwise.
