Im sorry for your loss. I had 3 missed miscarriages last year and a D&C with every one. Each time my body showed almost no sign of letting go so I unfortunately had to have the D&C. Its your body, you can choose to wait as long as you like before having the D&C, but be aware it could take weeks or even months to happen on its own. Your Dr has probably given you a couple of days to see if it happens on its own.

You said you dont want to cry in front of your kids, I understand that. Is there anywhere private you can go for a couple of minutes? Its really important to grieve because you are going through such an awful, traumatic experience. I know how hard this is.
