Are my progesterone levels too HIGH???

Willow - what is the role of progesterone?? The Dr only just gave me the results but didn't explain it (i guess she didn't have time or its not relevant for me to worry about)

Does it help sustain the pregnancy from miscarriage?? The higher it is the less likely you will miscarriage or is that not relevant cos it can change?

ren - I agree with the others, relax honey! If your dr was worried, she would have said something, and suggested a 2nd BT.
I don't know much about it all, but just try and relax.

I don't know all the biology behind it, but basically in a 'natural' prg progesterone is produced by the ovaries after the release of the egg. During an IVF prg, so many eggs are released by the follicles that the progesterone levels are usually high anyway, but progesterone is used in the TWW (in the form of an injectoin or pessaries) to support the pregnancy.

Low progesterone levels have been linked to miscarriage but when I asked my FS if we should continue with the progesterone after my postive BT he told me that studies had shown that continued use of artificial progesterone had no affect on pregnancy outcomes - so high levels of progesterone alone aren't going to be enough to stop m/c from occurring.

I found this:

Progesterone functions to inhibit the smooth muscle in the uterus from contracting and decreases prostaglandin formation, both of which allow the fetus to grow with the expanding uterus.

Hi Renstar

I just got a BFP a few days ago and also was wondering about progesterone levels - mine were 300 at 4 weeks and 2 days. I had been on progesterone pessaries and was told I didn't need to take them anymore. I also saw these normal ranges and wondered about my high levels - perhaps the answer is in the measuring units used? Probably an unlikely theory...

Ren don't panic about your levels. My levels were super high with Olivia and everything turned out fantastic. I read too much too and I had to stop as everything was scaring the crap out of me.
Best of luck with the next levels.
