1st US after starting stims

Well, had my 1st US Monday of this week after starting stims last Wed and looking good.  Have about 11 follies but looks like about 8 will make to mature size.  Most of those 8 are size 11-13 and the last three are between 8-10.  My estrogen level was elevated so I decreased the menopur from 2 vials to 1 vial per the nurses instructions.  I have f/u bld work and US tomorrow morning. ER planned for next Mon or Tue- might get exact date tomorrow.Sherry
