IUI #2 has a date

Ok so I went to my RE's office on friday and the nurse advised I basically have 4 follies!! So she told me she'd call me to tell me what units of follistim to take but it would prob be 150iu. So she called and told me it was going to be 75iu's...so of course i'm like WTF?? Last time we did the iui they started me out at 225 and dropped me to 75 and told me they stimmed me too fast and dropped me too low. So it was a bust. I can't believe this shit. I'm so aggravated. I mean this time it is different as I was on 300 for 5 days and 225 for 2 and now 75 for 3...so hopefully it'll still work. The more this cycle is screwy the less optimistic I am. My pg SIL stopped by today for the first time w/her 3.5 yr old. It was kind of hard to see her pg belly. For the first time it really bothered me to see a pg belly... i'm never like that. If this month doesn't work for me I am going to be a mess.
