Weird cycle. I don’t know what to do😩

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. I’m having cramps and back pain like my period is starting but it’s just spotting. A little blood when I wipe. Should I just take the provera and get my cycle restarted? Or should I just wait for a full cycle to come? But what if it never comes? & I’m suppose to start my femera again on cd3.
