Off Provera, When will my period start??

So this is kind of a long story so bare with me :) ok, I have been having regular periods each month, but the month before last I had light bleeding about 2 weeks after AF. My thoughts were that it was just ovulation bleeding. The next month AF was on time and normal, again at exactly 2 weeks later, i started bleeding again, only this time it was regular for the first couple days then got REALLY heavy (1 tampon/2hrs). I went to the Dr and he put me on a 10 day cycle of Provera to regulate it. As soon as I started taking it I stopped bleeding. There was maybe 1 day in there where I had VERY slight pink on the toilet paper but that was it. I have now been off Provera for 7 days and I still have no sign of AF coming. I have been reading through these forums and there's SO many different answers for basically the same thing. I am telling my story to see if I can get an answer for MY situation. If you have any idea please help. We are ttc. I have been unsuccessful in concieving for 5 years. Blood work is all normal, AF is always normal. And I can't get to a Dr to get the ultrasound done (I have moved 2 hours away from my ob-gyn). Any info would be GREATLY appreciated!!!

Thanks for reading, I will accept any input! :)
