Hi,
I agree with Ella, stop taking the herbs for a couple of days before you test your hormones.
Progesterone should be measured between cycle day 20-22 if you have a 28 day cycle (so basically one week before menstruation). Because then the Progesterone level is on it's highest.
Check out this chart, you will see that Progesterone (yellow color) is at it's highest in luteal phase, one week after ovulation resp. one week before menstruation. You need to know how much your Progesterone value can rise in luteal phase. To measure in follicular phase (like many do) doesn't make any sense, because as you can see in the diagram, Progesterone is low from cycle day 1-13 (without any fluctuations). But you want to know if you produce enough Progesterone in luteal phase and then you can also calculate the Progesterone / Estradiol ratio and you will know if you are estrogen dominant or not. Every woman has the same low Progesterone value in follicular phase, but not every woman can produce enough Progesterone in luteal phase. Some women produce just 3 ng/mL and others produce 20 ng/mL and you want to know how much you can produce.

You can measure other hormones like estradiol and testosterone on the same day.
