I am curious to ask... what happens to progesterone levels from the day of Ovulation to CD21??
And I'm asking because I have had a couple of CD21 blood tests and my levels were in the 30's, but this cycle I had a bt to confirm ovulation and it was quite different in results.
So what happens (or is supposed to happen) in those 7 days?
Do the levels rise, fall, stay the same??
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!

I just wanted to add a note to be careful to know the geographical source of the information when you're reading about good P4 levels. A lot of the sites I've read about it on are american and talk about anything over 15 being good. Unfortunately, the US uses different units (ng/ml) to measure P4 than we do here in Australia (nmol/ml). To convert from conventional units (US) to SI units (Australia) you multiply by 3.18... It took me a while to wrap my head around it.
On the subject of what happens between O and 7dpo, I believe the levels rise, but I'm basing that on what I've been told by other posters. I'd be interested to hear if you are able to confirm it.
