I personally have not researched what the number should be for progesterone but good signs of progesterone are creamy CM, lack of Acne in 2 ww, Steady high temps with out more than one temp drop near cover line during the main 2ww(not including the last day before AF), and lack of more than 8 hours of spotting before AF. Some women think they have a healthy LP because it is 14 days but they have 3 days of spotting before flow. Basically that means their progesterone has already fallen and basically they truly only have a 11 day LP that is healthy, not 14.
