I'm 15 I'm on birth control (implanon) I had sex on April 19th for the first time in about 9 months. The guy got off inside of me and every since then I've been really tired. I've had to pee alot more than usual. When I eat I always feel like I'm gonna get sick. I felt really dizzy a few days ago. And i've had mild headaches here and now. And I'm always hungry. Does anyone know what's wrong? And i've been bloated. I also haven't had a preiod since December
