Ovulation on Clomid?

LA

This is my first cycle on Clomid. (Days 3-7) Today is Cycle Day 17 for me and still haven't gotten a positive OPK. I ovulate on my own, but my doctor thought this would help us have a better chance of conceiving. This is what my BBT chart looks like. Can any of you ladies help, share your Clomid stories, or give me some insight? Yesterday, I had horrible horrible, like, doubled over pain in my ovaries, however, today, I feel fine.
