As the other ladies suggested it really is best to know for sure if you are Progesterone defficient. Have your doctor test you.
Transdermal application (through the skin) has been found to be one of the most effective ways to use natural progesterone. It is absorbed through the skin into the underlying fat which helps to slowly allow progesterone into the blood. This way of application helps the progesterone to be “time released” into the blood stream. To closely mimic the body’s progesterone cycle, it is best to use progesterone cream twice a day.
Natural progesterone cream is easily and quickly absorbed into the body through the skin (within seconds). So you can apply it essentially anywhere as long as you rotate locations of application.
The best areas for application are places that have capillary blood flow such as:
-Palms of hands and feet
When it comes to dosage, more is not better. Too much progesterone can cause hormonal imbalances, just like too little progesterone can. Dr. John Lee recommends a dosage of 15-30mg during the two weeks before your period.
Dr. Lee recommends that progesterone use begin directly after ovulation, which is usually day 12 in our cycles (twelve days after menstruation), and ending usage once menstruation begins. Once you become pregnant, stay on the progesterone.
