Is it possible to ovulate on my own before taking provera?

I've been taking the provera regimen for the last 10 months (10 mg CD 14-28). Before provera, i had a period every 3 months. I did ovulate before my periods. My Doctor prescribed provera, which now, I have a 28-29 day cycle. My last period started April 3rd. On April 14th I begin having watery, slippery CM and i was feeling very ual. I did BD on the 15th. I started my provera on the 17th. Is it possible that I ovulated this month? I know provera is giving to induce a period but I was just wondering could I have ovulated on time....thanks for any help!!
