you'd have to talk to an ob/gyn and have an internal exam done to be sure that the reproductive organs weren't damaged. odds are that everything is fine now.
The same thing happened to me, I think I was in the second grade or so and I was on top of the monkey bars and i slipped and fell right on the bar on my crotch. I was bleeding too and my school told my parents, i remember taking a bath and screaming because i had cut my vagina and it burnt so bad! I'm not sure if you have any serious problems though. You get pregnant from the inside through your uterus and I don't think you could have ruptured that or anything otherwise you would have major problems. If you do find that you have any problems let me know! Because I might have them too!
