Losing hope.

I haven’t had a period since November. I went months without one till May. I had a doctor appointment and they prescribed me Provera. It made my period come but was really light. The doctor said my uterus work and my ovaries do too just need a little help. So he told me to take Provera at the beginning of every month for 14 days. I don’t think I should be taking a hormone all the time. It effects my moods and I cramp really bad. Is there anything else I can do to try to ovulate. Is there anything that I can take to start my period the natural way like a vitamin. I really want another child.
