21 progesterone help!

Brea

2nd round of clomid and my 21 progesterone labs are rising, started with a 9, then a 12(pre clomid) , after my first round I was up to 15 and I got my results back today that’s this round it’s up to 21.5. I’m hoping this continues to indicate the medication is working. Do you all know the typically range that is considered “good” for progesterone levels in order to conceive and progress in a pregnancy? My md says over 10 but he still put me on clomid with a 12 , so I’m just wondering what’s an ideal progesterone level
