No AF since BCP - TTC

Since coming off the BCP last January, I've only had one period, which was in September. The Dr has prescribed provera, i'm now on my last two tablets and hoping for AF. In the mean time, I'm seeing the gynocologist next week. Has anybody experienced something simular and any idea what the gyno might suggest , do or prescribe? We are TTC by the way. It's kinda frustrating now!
