Hey I am using emerita's progesterone cream and took this from their website, you can check it out if you want, most of these creams are the same. www.emerita.com
"Women in their reproductive years: Pro-Gest® is best used during the second half of your menstrual cycle, for the two weeks prior to menstruation.
Days 1 (first day of bleeding) -13: do not use Pro-Gest®.
Days 14 - 21: use ¼ teaspoon twice a day.
Days 22-28: use ¼ to ½ teaspoon of Pro-Gest® twice a day.
The suggested use is based on a 28-day cycle. If your cycle is shorter or longer you may need to adjust the timing of use, earlier or later than day 14, to fit with ovulation. If your period begins early, STOP using the Pro-Gest® while you are bleeding. Count the first day of bleeding as day one, and begin the cycle again. "
you can apply it to your inner arms, inner thighs, abdomen, or chest, rotating the areas where applied
I make a little chart so I remember
Left inner thigh - Mon morn
right inner thigh - Mon eve
left inner arm- Tues morn
right inner arm
and then repeat
Hope this helps!
