Pcos supplements

I have beyond irregular periods (I only got 3 in 2017) and I just want to get them on track before TTC. I am currently on cd4 of a provera-induced cycle and I’m trying to find some supplements to take once the bleeding stops to promote ovulation and hopefully regulate me. I am on 500 mg of metformin. I also was going to try Vitex and Myo-Inositol because I heard they work well. Does anyone have any input or suggestions ? Any success stories using these?
