Should I get in trouble at school because...?

Ok so I was playing football with the guys, not because im butch or anything i just like playing around you know, just get away from the girls. Anyway there was another girl playing and she was on the other team. I was blocking her so I get the guy ( we were playing touch football btw) So when i blocked her i accedintly elbowed her . I didnt mean to but as soon as I was about to say sorry, She yells out She Gay She Gay. And im like yeah Im biual and proud, I have no shame in being what God made me. (She didnt hear this i was thinking, I didnt want to cause a scene so i just let her be) Next play i think it was the final ending it was 7 to 19. (My team had 19) and i was going in for a touchdown she trys to tackle me and i throw it to a friend and he gets a touchdown and we won. When the game was over she gets all pissed and what not and Im in the bathroom getting changed. She doesnt know im in the bathroom. She starts talking about me and I and I come out(not because she was talking about me but because i was done changing.) Then she gets in my face and says I need to take my d*ke @ss to a doctor because being is an illness. I looked at her in a weird way because most of the girls at my school have something(like STDs and I dont) Im a virgin and she says I try to sleep with every girl I see. I still didnt say anything. Then this other girl who is a follower gets all up in my face and then the first girl does to. The second girl is someone who is scared to fight me but the other girl isnt. She hit me first. I didnt even touch her! So the only reason I hit her was self defense. They the other girl trys to get me to and the only reason they one was because they jumpped on me, but seriously i wasnt even trying or caring about that i just wanted to go home. I have alot of pressure on me from my teachers and my great-grandmother. They all excpect good things from me like straight As and I try to get them but I cant and then the coach says that Im getting Iss maybe and the other girls to. I cant get Iss (in school suspention) It will go on my record which we show up in college and with that little mark I wont probably make it into a good college. So should I really be getting in trouble for this? I was only defending myself. Plus they dont even care, about getting in trouble, neither do their parents, but unlike them i want a future.
