Ovulation on Clomid

Hey y’all! Last month was my first month taking Clomid. I had waves of stomach pain on CD12 which I am thinking had to be ovulation. Blood test on day 21 last cycle confirmed I had ovulated—progesterone level was 43!

This is my second cycle on Clomid and I’m currently on CD16, but have not experienced the same type of stomach cramps I thought I would this month. Am worried that I haven’t ovulated this month. Or maybe it’s just later this month?

Has anyone experienced something similar??
