hi,
i am no expert on progesterone levels....but i have learnt that if you do get a BFP your level keeps increasing everday to help support the lining. when you ovulate your body produces it naturally.
i was told that a good reading is something over 30, but have also read anything over 16 is good too?? the other problem in regards to getting a BFP is the length of your luteal phase. it needs to be no less then 12 days.
the problem is everyone has different levels at different times in there cycle. i have problems ovulating and have had several day21 tests. mine are usual in the low 20's. i have done 12 months on clomid with no luck.
the last FET was also a BFN because i believe i was not given any progesterone support.
i am currently halfway through my TWW on my last FET. this time i am on pessaries twice a day. i am praying it does the trick!
goodluck!
