If Provera doesn't work what next?

Jessica

Tomorrow is my last day of my second try with Provera to bring on AF. I also took 28 days of estrace (estrogen) to thicken my uterine lining. The first try was back in March & was done without the medicine for my lining & it didn't work. I'm hoping & praying this works because my Dr. wants to start me right away on Clomid if it does. We want to TTC our 1st & have been trying for a year, but not ovulating & no periods.

What can I try next to bring on AF if this fails again?
