cycle day 44. no period or BFP.

So I was put on provera to jump start my period and then clomid to ovulate, idk if any of that has happpened because I get positive ovulation tests everyday since last month and pregnancy tests are negative. What should I do? Should I start taking provera again and clomid again to try again? I have a appointment at the end of the month to see what's going on. Put anyone else experience this? I was also diagnosed with PCOS. so idk if that's why this is happening?
