Sex hurts :/

Me
Saturday I supposedly had my "period". I've had really bad cramps and my boobs hurt a lot. That same day I took a shower and blood like chunks came out with this pinch in my stomach. Yesterday I tried a couple of times to pee and while at it I almost fainted.. I bearly made it to my bed. The feeling to pee hasn't stoped and it hurts. My period stoped too and I just have really bad cramps. I can't have sex without my vagina hurting... What do you girls suggest? I'm already making an appointment for my doctor tomorrow to see what's going on. But I want to know at least where I'm at.
