Pregnancy Info HOME

Ok, I'm 18 and have been recently "fooling around" with my boyfriend of 2 years. Two nights ago he went inside me, not all the way but very close(we have done that a few times lately). It hurt and we kept messing around and he stopped trying to put it in. Then after we were done I went to the bathroom and I was bleeding just a little bit and it kinda hurt to sit down. So i wore a panty liner to bed just incase it bled anymore. Then yesterday morning I was still bleeding so I thought..maybe I started my period 2 weeks early..so i put a tampon in. Then last night the bleeding stopped again so I didnt wear one to bed. So then this morning I'm at college and I go to the bathroom and im heavily bleeding. So now I know I'm on my period. My question is why did I start my period a week and a half early? and does that mean he ripped the hymen or whatever its called?? I'm starting to get worried. Please tell me whats going on.
