Hi all - well a BFN today 11 days after my IUI. This was my 3rd round of Follistim. Although I have had 3 MCs, I have never gone two cycles without conceiving on Clomid only. Now I am on Follstim and HCG which is way more expensive. One part of this switch is so annoying, on Clomid I would get scanned to see if I released or not. But on HCG they scan me to pick a trigger day, but never scan on IUI day. I know the whole 36 hours thing but how am I supposed to know how many follicles I had? If we caught it? If I even released? Clomid made me crazy/depressed but it worked. Any advice or similar experience?
