Fertility blood tests - what do they mean?

[Disco3000]

I had a full blood work up to test for potential issues around infertility, most results were normal but one came in at 11 and the normal levels are 20 to 150. I can't remember what this was for, does anyone know?

Might be progesterone. Did you have your bloods done a few days after ovulation, as the level begins to rise then? This is usually done as a day 21 test and you’re aiming for 30 or more for a sign that you ovulated.

Of course it could be something completely different!
