Low BBT and Provera

Tori
Prior to this cycle, I ovulated monthly but I had short cycles (25 days long, 3 day period, 8-10 day luteal phase ). My gyn started me on Provera 10 mg for 10 days starting on the first day of my cycle. My period was 6 days this time but my temps have been super low and I'm worried that I didn't ovulate and can't get pregnant. I had other ovulation related signs this week though and today is CD 19. Anyone else experience this?
