any suggestions?

Hey, so I'm 19 therefore I've had my period for more than a couple years now. And I can't get into the lady doc till august. I cramp and have period signs for at least 2.5 weeks out of each month and I have my period for 1-2 days. I also used to bleed durning sex in certain positions. I know none of you are doctors and I know I need to get in. But do you guys have any segregation sad to what it might be? My mom says I might have cysts on my ovaries because she did when she was younger
