    Plesa tell me day 21 my progestrone level is 28 and my age is 34 please tell me this is good or not.

    Hello I had a progesterone level of .33 on day 13 of a 32 day cycle my doctor has put me on 100 mL or milligrams of progesterone cream to be used on the day after ovulation until my next. Can you tell me if that level is low as I noticed that after inputting the figures in your calculator it said that anything under 1.5 was normal during the follicular phase but it also noted that a pregnancy in the first trimester would be unviable is this suggesting that I would have no chance of getting pregnant if my levels are what they are now ?
