I'm 15 . Me and this guy messed around . We didn't have actual sex , but attempted to put it in several times. The penis and vagina was touching a lot . This was about a week ago and this week I've been hanging cramps , stomaches , feeling really sick like throwing up . Getting hot and cold . A little dizzyness . I have brown discharge. Very hungry but when I eat I feel sick . I get tired after doing anything. Sleeping and napping a lot . Is it possible I'm pregnant? Please answer me :]
