Medroxyprogesterone help!

I've been on a medroxyprogesterone and clomid cycle for 3 months now.... first 2 months took the medro for 10 days, started my period, then clomid for 5 day. No luck YET. But this 3rd month, I took the medro my normal 10 days... waited and waited, but no period... and no pregnancy. 😥. The doc started me on another 10 day medro run... same result. What in the world is going on with my body? Any advise would help. Doc tells me to be patient, but I am seriously freaking out. Has anyone ever experienced this?
