Progesterone Level Help!

Hello ladies, 
        I started my first round of Clomid 50mg, this month and had bloodwork done on CD 21. My progesterone level was 25.7 ng/ml. I have not heard from my OB yet but I wanted to know if this level is considered to be in the "normal" range? I just want to have a better idea of what I'm dealing with. Thank you so much
