Don't feel like that was a stupid question. I remember the night before my d&c and I was terrified. Ask all the questions you want! I hope you are able to get some sleep tonight.
My dh asked the doctor if he would give me something to help me sleep. I had not slept since finding out about the m/c. I only took it 2 days but it was nice to have so I could get some sleep.Feel free to cry as much as you want. It is really a painful time and you need to let yourself hurt. Using this board helped. I felt like I wasn't alone and that what I was feeling was normal.
