ok i have a very irregular period it comes like every 3 months and i never know when it will. i had it at the begging of the month and now im having it again. by far this is the worst ive had it because know matter what i do or how frequently i change tampons it bleeds through alot. i had to come home from school yesterday.

what could it be? but more importantly how can it stop and is it normal?

i play sports if it helps and im 13 and not sexually active
