I have PCOS and can't get my hormonal acne under control, it's affecting every aspect of my life and I need help. Advice?

I've been dealing with hormonal acne on my face & back for years and after blood work I was diagnosed with PCOS. I've been to many dermatologists but all they do is prescribe tons of antibiotics and clindamycin gel. OBGYN put me on birth control pills but I had terrible side affects and had to stop. Tried different bc pills too, nothing helped. I go to Mexico to buy Retina which works well but I still break out. Tried spironolactone, had a heavy period EVERY single day. Please help, thank you!
