Sorry for taking so long to reply. I have no idea why I was on them twice a day? sorry can't help you out with that one. I spent the TWW on the Crinone, then after the +ve test, I was switched to the pessaries twice a day. I had to travel a bit, and had 2 different FS, one who did the EPU and transfer and the other one looked after everything else.

sorry I can't help you out anymore than that..
