Skipped AF in July- not pregnant

Dr put me on Provera, for five days, to reset the cycle. I was so hoping for good news, but it's this instead. He said it's difficult after 35 (i'm 37 next month).

I didn't feel this would be so hard before the visit. Now I'm worried I'm too old. My son is 14-there was no plan for him, and a one time shot! This time, just off the bc and seven months of trying. I wasn't stressed before. Feeling like my body isn't working right.

The doctor was great, helped me set a plan with husand.

I know others are going through this. What can I expect, real world, from the Provera? Any advice otherwise- supplements?
