Step one is to get a baseline of where your progesterone levels are currently at through testing. We want to see serum progesterone levels ideally above 12 (I like to see them above 15) in the luteal phase to confirm optimal progesterone levels.
Ideally, progesterone should be applied and absorbed vaginally—absorption of progesterone through the mucous epithelial membranes of your labia is much more effective than through skin.
Dosage and timing are all dependent on where your progesterone levels are currently, and what your goals are—whether you’d like to get pregnant or not, or if you’re trying to manage symptoms of low progesterone,
