Okay I'm 19 years old. I've been having weird symptoms and I don’t know what it is maybe the flu but I am scared.. but maybe I'm worrying for nothing. I had unprotected sex....3 days in July 17th 18th 19th 2005 but my Boyfriend pulled-out all 4 times. I was 12 days late on my period; I Started bleeding very lightly at first then it got a little heavier, then light again it was pinkish it last for two days ,and some discharge..more then normal, only one day of cramping. This past week I been feeling Nausea only at nights and I have been feeling super tired this whole week. my breasts are VERY! sore past two weeks.. I have been getting headaches and dizziness a day, and I been moody like: sad, happy, cry and angry. I have been feeling Fluttering or butterflies in my stomach to. using the bathroom alot lately to, I just need some help to figure out what to do next.
