Hi I'm new to this board but not Follistim, I take mine starting day 3, the days my RE has me come in for bloodwork and u/s depends on how I'm progressing, my first is normally 4-5 days after the first shot, then its usually every other day. My arms usually ache from the blood draws by the end of the month.
