Help!!!

I had a D&C in October... Six weeks later still no period. My doctor gave me Provera and I had a small period... Then the following month no period. Doctor gave me Estrodial and Provera I had a small/spotting period.. I should have started a few days ago and nothing... Plus negative pregnancy test. What do I do?? I just want my body to have a period so I can ovulate and we can try for a baby!
