Provera bleeding and femera

Meg
So I have PCOS and I took provera this month to start my period. My period showed up 5 days after I stopped taking it and I had heavy flow for 5 days. But ever since then I have had spotting...and its been 2 weeks since CD1. I took femera cd3-7 and still haven't had a positive ovulation test. Has anyone similar bleeding with provera? I feel like nothing's happening with femera too. Any success? And how much femera?
