Yes, I had a polyp removed about three years ago and had the same procedure done. I was having very heavy bleeding with my periods. The D&C is very easy to cope with, at least I found it to be. I was only in the hospital for about 6 hours from admissions to release. Only had a minimal amount of bleeding that day and just some slight cramping and went about my usual routine the following day. My polyp was benign, and I had many new ones forming which my doctor removed. He also showed me the pictures he'd taken of my uterus before and after, it's quite amazing.
So, rest assured that you're doing the right thing by having the D&C and stay confident that everything will turn out alright. Best of luck!
