I completely understand as well. I had two D&Cs in two months related to the same pregnancy. I had the first D&C on February 19 (for the miscarriage) and then at the follow-up ultrasound two weeks later they found a sizeable blood clot that had to be removed, so I had another D&C and hysteroscopy in April. The follow-up after that was normal.
After the first D&C, he told me I could have sex in two weeks, but to wait to TTC for two cycles. After the second D&C, he told me I could have sex in two weeks but two wait one cycle to TTC.
Unfortunately, my cycles haven't been the same since. The first three were five weeks apart and this one is dragging on FOREVER. So TTC doesn't even look possible until this stupid cycle decides to end, and since there's no O, we have no clue when AF is supposed to come.
So I completely understand your frustration. I am sorry for your loss and I wish you the best of luck in TTC. If you ever want someone to talk to, please feel free to PM me.
