Hmmm, maybe she said 7 days past AF because they want to see what your levels are at before you O to see if that's what it big issue is. Does that make sense? I'm confused now too...
I found this info for you...
Progesterone levels after ovulation (midluteal, middle of the second half of the cycle) in a nonpregnant patient are generally at least 8-10 ng/ml. Much lower levels usually mean you did not ovulate. Progesterone levels can change from one day to the other, from one hour to the next, from one laboratory to the next. After you eat, progesterone levels can drop by as much as 50%, that's why the blood test should be done in the morning and before you eat. Progesterone levels are usually well below 5-10 ng/ml without ovulation. If you are pregnant, progesterone levels are usually at least 10-12 ng/ml to have a better chance of a good pregnancy outcome and most doctors like to see progesterone levels around 16-18 ng/ml or more though there are many successful pregnancies with lower levels.
