Lanea, I had two miscarriages over 18 years ago and you never forget. Mine were at 10 weeks and 18 weeks and I, too, had seen the 2nd baby on ultrasound (trying to determine due date) and when they retested a couple weeks later, the baby had died. That was hard. I did already have a daughter and I think that made it easier for me.
One thing everyone did tell me (way before I ever got pregnant)was to wait to buy stuff and tell people. (When I later got pregnant with my son, I didn't tell anyone until I was 5 months pregnant! After two miscarriages, I just didn't want everyone to know if it happened again.) My doctors told me that miscarriage happens a lot and in most cases the reasons are a mystery. This kept me from going crazy dissecting my every move, meal and thought!
But, I still remember it all and my kids know about it-- I never considered it a "taboo" subject and it's part of our family history.
Perhaps you can get someone to store your baby stuff for you--or put it in the attic or somewhere. It is fine to mourn your loss because it is a big loss, but don't get stuck there. I have known women who went near crazy over a miscarriage--never working through the grief, resenting anyone else who was pregnant, and so on. That's just not healthy.
My sympathies are with you during this time, and I wish you a full and quick recovery.
