Late ovulation on clomid

Hello Clomid ladies i am on cycle day 30 on clomid 50 mg day 3 - 7. This is my 1st clomid cycle and all new to me. I have very irregular cycle and probably don't ovulate on my own. Clear blue advance digital still shows flashing smiley goin on day 11. Obgyn doesn't have patience and is of little help. What could this possibly and how long should i wait to start provera to induce period. I am tired of waiting! Help!
