CD 105- AF finally came!!

I went of the pill in March and we have been TTC right away. I had withdrawal bleeding, but no AF for 105 days and countless BFNs!!! 
I went to the doctor two weeks ago (convinced that something was terribly wrong), but blood work came back normal! She gave me Provera. I had planned to start it in July because I am going to the beach for a week and figured i'd get my period on vacation if I started it already. Ironically, AF came on its own, two days before the beach! Not so great timing, but I'm sort of happy my body did it on its own! I've been feeling kind of sterile.  I just hope I ovulate this time and have a fair shot at conceiving. I'm not up for another 105 day cycle and all the craziness that goes along with being irregular.
