Clomid & Progesterone level

Brit

I see everyone posting that their OB or fertility specialist wants their progesterone to be 15-20 or higher; however, my progesterone was 8.2 and my OB was totally happy. Anyone else’s OB good with those levels? After all progesterone fluctuates hour by hour and can range drastically in a day. Anything over 3 indicates you ovulated (although I also know 10+ is usually indicated to maintain uterine lining allowing successful implantation and early pregnancy).

PS—as an experiment I got it checked out 2d later and it was >10.

Just interested in hearing all the different treatment plans as medicine is an art and not exact at times.
