Problems? Doctor didn't help..

I never use this lightly. It's not a joke and I'm Bering serious.. i was raped about 2 and a half weeks ago, unprotected during spring break...Parents know, doctor knows, police have been involved.. He has a girlfriend, so I'm not sure if I should be the one to tell her or just leave it in the past. But he told me that it wasn't rape. I told him I didn't want to do it, no and to stop. When I pushed away, he grabbed pants and pulled me back on him. My problem is my body is acting weird now, and I don't know what it is. Maybe I'm just overreacting. My periods suppose to start in 9 days and my body has been acting strange. Could it be related to pregnancy? While I was transferring from one class to the next, I had ringing in my ears and lost all strength in my body. But was still able to keep walking, slowly. During softball practice I felt weak and lightheaded. It's been lasting for a couple days. Today I feel better. My doctor said its too soon to test for pregnancy, which I knew. But my doctor was also unable to tell why my body has been acting like this besides bringing up dehydration or allergies (Florida pollen). Am I over thinking this?
