What to do!?

On April I decided to start birth control pills because my gynecologist said it would help remove my cysts my period was from April 12-15 I started birth control pills from April 14-21 I stopped within a week because they made me very ill. Had withdrawal bleeding from April 24-27. Had AF on May from 19-22 and just got my period today June 20th. So the first time I had o wait roughly 38 days for AF and this time around 33 days. My question is when will I start ovulation I'm confuses and I really want to get pregnant been TTC for a long time with no luck and a miscarriage at 4w3d last year. I'm never getting pregnant is what I feel right now. :'(
