H.M.
I am so sorry for you as I understand the pain. I micscarried my 1st pregnancy and was so saddened by by the experience. I understand feeling connected to the baby. Please keep in mind that people don't always know what to say at a loss and that they are trying to help you to feel better even if they are making it worse.
By the way I did not have to have a D&C and had 1 period and got pregnant the next cycle with a full term pregnancy.
