PCOS at 17

I’m 17 and was diagnosed with PCOS a few months ago. The doctor has me taking pills to kick start my period but I’m getting tired of taking them. Before 2020 I didn’t have a period for a year after I stopped my birth control. So basically I didn’t have a period in 2019 at all. I don’t know what to do to fix it. Does anyone have advice for my next step?
