Hi everyone!
Basically, during an IUI cycle, I had a high number of large-ish follicles, but based on the bloodwork, but doctor continued with the IUI cycle anyway. I was a little worried about HOM.
Anyway, The cycle was a success (yay!) and I had my first (early) ultrasound. I was only about 5 weeks, so nothing is definitive, but it looks like there is only one little bean in there. I'll have another U/S on Thursday, which will hopefully be more definitive. I'll reply to this thread with an update if folks are interested

Hopefully this helps people make a decision going forward.
