Miscarriage...now a failed IUI

I'm so fucking furious that I just pissed away $1500 to a quack doctor who failed help me get pregnant.  I had a huge follicle and a handful of other large ones, and my bf gave an unusually large number of viable, motile sperm.  We're both healthy otherwise.  My original due date from the pregnancy I lost at 8 weeks is July 25.  I feel like this will never happen.  Why am I being punished???
