Athletes with horrible period problems

I have had a history of horrible periods and cramps. Within the last 2 years I have also been getting cysts on my ovaries,they all go away eventually. Since my periods have been irregular and horrible cramping I was but on the pill. But the thing is i am on a conmpetive drumline,we workout and rehearse 4 days a week. I have to keep up with 15 guys,there's no room for cramps ect. What do other athletic girls do?
