Progesterone level??

Rachel

On my 2nd round of clomid 100mg. Everything I’ve read has said day 21 should be above 10 to indicate ovulation. This round it was 7.5 and my dr said as long as it’s above 7 they’re happy. I know every lab can have different ranges but 7 just seems low. Anybody heard differently from their dr? Or had a BFP from a 7 progesterone level?
