Dusty,

I had the pregnyl in my last 2 cycles.. every 2nd day to help with the Gonal F, and then 3 times during the 2ww to support the crinone.... the messing around with snapping the vials, etc is a little daunting at first, but you get used to it!

I found I had much more EWCM with the pregnyl... and a lot more discomfort in regards to the ovaries feeling really swollen.
(But it was worth it - it was the difference between getting 5 and 7 eggs the first 2 cycles, and 18 eggs in the last 2 cycles)
Make sure you're drinking bucketloads of water!!!
... Oh, and you have LOTS of packets of liners in the house
