Clomid and IUI fail

I am so disappointed. After ttc for 2 1/2 years with a mc one year in at 8w, I finally do clomid. I go to 4 doctor visits total for the month. One perfect egg and nothing. I am sad, mad (I had to pay a lot of $$), and just so disappointed. I figured it wouldn't happen, but I had hope. I am so disheartened. Now the whole cycle starts again and we'll try again. I just want my rainbow!
