From no period to long period to Provera to BC

I don't know how common this is but I went 62 days without a period. When it finally decided to show, I am now on Day 32 and miserable. One week ago my doctor prescribed Provera to "jump start" my cycle but all it did was make me bleed more. The more I bled the more lining kept coming out. I am now taking orthotricyclen lo to regulate my period again, but I feel like there is no end in sight. I have had a D&C before because of thick lining. I'm just feeling lost and bloated and broken.
