Clomid side effects around ovulation?

samantha
The only way I know my clomid is working is the side effects from cd 10 to cd 20. I usually get crampy and on ovulation day I get dizzy and really warm with hot flashes. I knew my 2nd cycle at 50mg was different since I had no side effects. My progesterone was only at 6, whereas my first cycle was a 13. How do you know your clomid is working/making you ovulate?
