Hello Ladies!
Firstly,

to BabyBella!!! I'm glad you are joining us! To answer your questions, I would definitely ask for at least one, if not two u/s. My doc does a baseline CD3 and then another on CD10, then monitors me every other day or so from then until I surge. As to the timing, I actually had my first IUI the day of the surge. If you are using your natural LH surge as the timer then some docs prefer to do IUI same day. Reason for this, I was told, is that you can't detect the surge until 4 hours after it has happened, and sometimes you may have surged much sooner than that and are detecting it late. Also, with sperm that has low motility (which is most frozen DS) it's better to do the IUI day of LH surge because it gives the slow swimmers time to get to the tube and be there when the egg arrives rather than getting there after its arrived. Anyway, I hope this helps, and again WELCOME!!!
Styltryn, no worries! If your baseline was without stims then 4 antral follies is really really good. In fact, it's textbook. All women produce an average of four antral follies at the beginning of the cycle...with a natural cycle one will become the dominant follie and the other will fade away. With stims you make more antral follies and in theory none fade cuz youre feeding them extra growth hormone so I think you are in good shape especially with such EXCELLENT BW!!! Congrats!!! As to the protocol, it sounds normal to me. I read that some docs start a day later...the theory goes earlier stimming makes bigger follies while later stimming makes more follies. Anyway, it sounds like he knows what he is doing so try not to worry. Time to go get a nice cup of rasberry leaf tea and do some serious relaxing. I hope the cousin isn't making a nuissance of himself.
Susan, congrats on a great follie! I hope you are OPKing often as it sounds like you're going to surge any minute!! I have

for your IUI this weekend! please keep us posted on how you go!!
Hugs to all!!!! Time for me to go do some work.
Cheers!
