First cycle of clomid

So this was my first cycle using clomid. My Dr. Had me do provera to bring on a period...10 days 10mg which worked like a charm. My period started the day I took my last pill. Then I did clomid 50mg days 5-9. My Dr. said to start using opk on cycle day 11-17 or until I detect ovulation. She said cycle day 14 is when she expected it to show. Well it hasn't yet. She wants me to start provera again on cycle day 35 if I get a negative pregnancy test but shouldn't that date be pushed back if I ovulate later? Here is a picture of all of my ovulation tests...am I getting closer to getting a positive?
