Confusing cycle

So I’m a little confused as to what’s going on with my body. I took femara this cycle but never got a positive opk. I had spotting cd 17-19 and cd 27-28. My dr gave me provera to take starting day 28 since I hadnt ovulated. I took one provera on day 28 then woke up on day 29 and I had a positive opk. I didnt take anymore provera since I got the positive. Woke up on cd 32 with cramps, and back pain and spotting again...same today with cd 33. Idk what to do now. Should I just take the provera and get my cycle restarted?
