Day 21 Progestrone

Currently on my first cycle of 50mg Clomid.

Scan on day 12 showed I had a 21mm follicle and a 17mm follicle.

I had my day 21 blood test done yesterday, awaiting the results today. What should I be looking for? What’s a good result?

Any similar experiences anyone can share?

Thanks in advance 😁 x
