Right so where to start... Well my boyfriend of six months and I have had unprotected sex several time sometimes he finished sometimes he didn't. (Before you freak out we are both clean and have gotten tested and I'm on birth control). Friday the 13th I began feel sick to my stomach and having some cravings, However on the 14th I wrecked my truck and got grounded so maybe its just stress??? But today is the 17th the sickness has been going strong, I've had to use the restroom more often, I don't want chicken (normally the only food I want), I'm smelling things I normal don't smell or mind smelling, and my jeans are starting to get tighter.... My period was supposed to begin around the 15th and end around the 21st and again its already the 17th. So a little help is need since I'm only 17 and have no clue what to do.
