My wife had her blood test today and her progesterone level took a nose dive from 40 to 16. Its slightly lower than the # they'd like to see which is 20. We were told not to worry and that progesterone levels are pulsitile, which means that it goes up and down all day long and that they could have just caught it at a low moment. They want us to bump up the dosage from 1 to 1.5 cc tonight. Anyone else have their progesterone #'s fluctuate like this? Thanks!
