Ovarian Cyst. #OUCH

Alexis
I've called my doctor multiple times and they have yet to call me back. 
I have multiple cysts on my rift ovary, and it's causing me pain. I was told that if I go back on th birth control the cysts will be less of a bother. Last time I was on birth control I broke out into rashes all on my body. I was told that there are pills out there that will schedule my period to come every 3 months. I've tried calling my doctor and I keep getting told she will call me back the next day, or they will keep me on hold for 20mins and then they will hang up the phone. 
My period is my worst enemy. It lasts for 10 HEAVY long days, along with 24/7 VERY VERY VERY painful cramps. I'm at a loss. Any suggestions?
