Trying for a baby

Tee

I have to take Provera to help start my period every month for 14 days. The doctor told me my olveries work they just need a little help. I want at least one more baby but feel like I can’t get pregnant. What do I need to do ??? If I take the one a day prenatal vitamins will it give me a extra boost ?? Or do I need to find something else that’s in store and don’t need a prescription for. Is there something natural I can take or do ??
