Question
Question: 1. Does breastfeeding cause progesterone levels to be lower? What's a normal/healthy range?
Question: 2. Would weaning help protect my new pregancy (at 5 wks. currently) since my levels were 18 before taking 10% progesterone gel and dropped to 14 only 3 days later, after starting progesterone gel?

Answer
Dear Sandy,
Regarding your first question no information was found.
With regards to progesterone levels early in pregnancy, some experts see 20 ng/ml as a desirable level; however, many of us feel more comfortable with a level greater than 25. In your case, I recommend you consider progesterone in oil, 200 mg intramuscular injections twice a week. A “trough” level should be measured every two weeks. A trough level measures the hormone when it is at its lowest, that is, right before the next shot is due (or 3-4 days after the last shot in the case of twice weekly regimens).
