Just found out I hadn't miscarriage

Victoria • Married 10 years. Mommy to James and Jack 💙 pregnant with #3 due October 24th
Went for my 12 week check up today and was told baby stopped growing at 9 and a half weeks. I have had no bleeding, no cramping, no signs at all. I'm getting a d&c performed on Friday and was wondering if any of you have had one done? I'm nervous about it.
