Okay so I'll try to shorten this as best I can. I unwillingly had unprotected "sex".. 2 days later I took a emergency contraceptive.. Then about a week later I got a heavy period that lasted about 4 days.. It was about a week and a half early. I haven't had my period since.. It's been 3 months. Ive taken 4 pregnancy tests all negative spread out throughout this time. Why hasn't my period come? I don't know if this matters but I used to take birth control for other reasons. I was very choppy and irresponsible taking it and it messed up my system and my periods were extremely irregular when id stop using it. Then when I completely stopped I didn't get my period for more than 6 months.. Then I had a few periods on track then this whole thing happened. So could that have anything to do with it? Please help I'm so scared I have no pregnancy signs but my period has been gone for so long!

Time to see a doctor!

What do you mean when you say you "unwillingly had unprotected sex"?

It is certainly possible this is a side effect of the emergency contraceptive. But its time to see your doctor. At 15 you should be able to talk to your OB/Gyn without your parents presence.

The phrase unwillingly had unprotected "sex" sounds like rape to me. Is that what happened?

Yes that's pretty much what happened... He abused me but I don't want anyone to know about that part because it would cause too much stress right now that I can't handle. I don't know if I can trust the doctors not to say anything to my parents or have anyway of letting them find out

If someone raped you, they need to go to jail for doing so. It is not your fault that this happened and you should report them for it.

What you tell a doctor is supposed to be confidential, even from your parents. To relieve your mind, ask him if it will be before you tell him anything. If he thinks he has to tell them, he must ask you for permission first.

Unfortunately there is no proof of rape at this point. So I don't see where reporting it is going to do much good.

Like I said, I think you can talk to your OB/Gyn in private and have your confidence kept. But the bottom line is, if your period is not coming there could be damage to your body and you NEED to be checked out.
