I was right, my RE does operate under the mindset that in 'most' cases if you address the immature follie issue and get a nice, plump, mature follicle the progesterone issue will 9 out of 10 times correct itself. I definitely had low progesterone. Then on Clomid, once we got the dose figure out my progesterone was normal and my luteal phase extended from 11 days to 14 days! So Sis, you may be just fine. Especially if you had some Femara lingering helping those follies to mature. Progesterone has to be used with IVF, but with IUI or even just natural cycles it is not always a necessity. Docs just like to be safe than sorry. It doesn't hurt the woman to put her on progesterone... Well other than her pocketbook if she doesn't have insurance.
My nurse told me that my number would have to be below 10 before they put me on supplements.
So you may be just fine without it.. Some women do have a progesterone issue even after producing a mature egg, but this is an exception rather than the norm from what I have been told.
