Hi Kmond.. Congrats on your PG hun.. With regards to your progesterone levels, the way I look at it is that with all the messing around that they do with our hormones is that the pessaries kind of fill the gap between what our bodies normally do and what the FS has been making them do.. So once you're PG your body takes over this production without FS help and if it is within natures ability to keep you PG then you will be but the will of the FS will only help so far.. Good luck sweetie.. I hope nature continues to carry you down the path to a H&H PG... (I hope that makes sense)
