I just did a bit of a google and so far from what I have read it seems a low progesterone level has a risk of miscarriage. So I am not sure what a high level would mean. The levels that are normal according to this source are:
Day 15-28 2-28 ng/ml

It also says progesterone prepares the lining and keeps it thick, creates the cervical plug and prevents the uterus from having contractions. Nothing bad in all that!!

Another article said that there is no upper limit for progesterone so it sounds like you can't have a level that is too high??

I hope you get to go with this cycle as I know what it took for you to get back on that horse! Good luck!
