I went in for morning monitoring this morning after 3 days of Gonal-F (70iu). The doctor said I had 2 follies at 13, 4 or 5 at 11, and a bunch at 10. She told me that they would probably keep me at the same dosage and have me come back the day after tomorrow. She assured me that they won't all grow at the same rate so I wasn't going to end up with 20 babies. (This is not my doctor, but another doctor at the practice). The nurse called me (again, not my nurse... she had the morning shift) and told me to lower my dosage to 37.5 (because that's the lowest my pen will go, otherwise she would have had me go lower) and to come back in the morning if I could make it in the snow. The problem is... my local office is closed in observance of Christmas tomorrow (which doesn't make sense to me, as they were open today) so I would have to drive an hour to get to the open office... and there's a blizzard outside. I told her that there was no way I'd be able to make it that far in this snow... I don't have four wheel drive. She said that she just has to tell me to come and that, if I can't, to call back in the morning. The doctor would review my results again, probably have me continue the lower dosage, and then come back the following day.
I'm afraid they are going to have to cancel the cycle
If they do cancel it, I know it's for the best.. it's just frustrating. I feel like we've been waiting to get started for so long (waiting for the appt... then I had to go on BCP until the doctor determined that I had an arcuate uterus instead of a septum). It sucks that when we finally got started on our first medicated IUI cycle that it might get canceled. Vent over.

Re: I think I'm overresponding
That sucks. That does sound like a lot of follies. That's not unlike what I had for my IVF cycle. Damn snowstorm.
Have you done Clomid? Or did they move you straight to injects + IUI?

I hope they don't have to cancel you. Lowering the dose will probably help slow down the smaller follies. You still have to get to at least 18-ish before you would trigger so that will give you a few days since the follies grow at 1-2mm a day. Sucks that this blizzard isn't timed very well for you, but I think you will be ok if you go in on Tuesday. They will also look at your b/w to determine how many of those follies could potentially be mature so you may not have quite as many as it seems as you get closer.
Good luck!
They didn't want me to do Clomid because my lining was pretty thin to begin with so the doctor didn't think I would do well on it.
Thanks everyone... I know I am jumping to conclusions a little early in the game. Hopefully lowering the dosage will slow some of the follies down. Damn overachieving right ovary!

Be kinder than necessary, for everyone you meet is fighting some kind of battle.
That really stinks. I overstimulated on my first Follistim cycle as well. They really didn't think all the follies would continue to grow, but I ended up with what looked like a "perfect IVF" cycle, so we had to cancel. I cried and cried and cried over the cancelled cycle, so I know where you're coming from.
I hope some of your select out and its not cancelled.
