Miscarriage...now a failed IUI

Carrie • M/C 12/2016 • TFMR 12/2017 • M/C 7/2018 Baby girl born 12/27/19 Baby boy due 12/19/21
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???
