If you have PCOS, why the heck are you not on metformin? Or metformin with clomid? And why the IUI's? Is there male factor involved?
If you know all about metformin and for some reason it just doesn't work for you, then sorry for butting in, im not trying to be a witch here, but it sounds to me like you are on the WAY outdated, wrong protocol for infertility related to PCOS, and I juat wanted to make sure you knoew that metformin should be the first line of treatment for a woman with PCOS, because some women have doctors who are so far behind, they have them doing less-effective, outdated treatment, when they could be using much easier, less invasive, cutting edge treatment.
I personally am getting ready to have number 2....we use metformin, sometimes with clomid, if my cycles are longish, and thyroid meds for my thyroid condition, and an EXTENSIVE vitamin regimen for dh, who has sperm issues. It is a daunting prospect...but for me, the prospect of possibly having hyperemesis again, and doing nothing but feeling like crap and puking my guts out for 5 fricken months, ...but this time with a toddler to chase around....THAT is what is scaring me....oh, and the thought of another hellishly painful birth.
The actualy conception.....doesn't worry me so much, LOL!
