Cycle

I’ve only had 1 af since March do to coming of the depo shot . My doctor gave me provera to start af which it did lasted 4 days but now it’s been 36 days and my next one should have started by now. My doctor told me she won’t do anything else till February if I’m still not having my period. So I’m thinking of getting something over the counter to maybe help regulate my cycle. I’ve been told about vitex and maca is there anything else I could try? Do I need to be taking these one at a time or can I use multiple at once to up my chances? Any advice would be wonderful
