eponagirl,

My wife's physician uses a blood test for progesterone levels as did mine for male hormones. The saliva tests are considered less accurate by many. The cream is also available in tube form or in a small jar with a small measuring spoon. It is important to apply it properly because there are some areas of the skin that do not absorb it properly. I put my Testosterone cream on my butt cheek.

From the improvements you are realizing, it sounds like you may benefit from a full hormone panel. Progesterone needs to be properly balanced with estrogen, etc. My wife has friends who have benefited greatly from Bio-identical Hormone Replacement Therapy starting in their early thirties.

It sounds like you are using bio-identical progesterone. Good for you. Otherwise it would be sold as a brand name synthetic that is claimed to be similar to progesterone. Bio-identical hormones are synthetics that are chemically exactly the same as the human form.
