Hey Fi, welcome to BB and our little IUI thread....
As Belinda said I had a high progesterone level of 78 on my first IUI cycle.
This was due to the amount of hormone in my body which would have meant that I ovulated more than one egg.
Unfortunately there is no way of knowing if you can be PG with a high level, but I agree that maybe you should ring the clinic and speak to one of the nurses.
Good luck and I hope the TWW goes really fast for you...the last week is a killer..so come in and have a chat...it helps the time go faster.

Belinda and Kaydee, how you ladies going? Not too long now!!
