Hi , I am going through the same thing . I had unprotected sex on the 13th of this month, he pre-cummed in me, and it was dripping down my leg I was afraid that he "you know" inside of me , yess we had sex for awhile and he was afraid to tell me he did, the next day he told me he did only bc he was afraid to say so, and the da day after I bled really bright red so I was confused bc my period was due that same wensday. And I bled diff colors until the weekend it stopped, I was happy bc I was like it prob. Just came early but now I notice that I didn't have sore bbs usually my boobs get really sore !!! And in the past couple weeks I've had woken up at 3am and I had uncomfortable cramping

and now I'm moody and my back hurts, I woke out in my fitness class with weights and I had really bad stomach pain , and my stomach sticks out even though I suck in, maybe I'm bloated but it feels hard. Weird stuff been happening .my back hurts right now. Well I am 18 going on 19 this year!!!! Young but an adult. So what do you guys think?
