Blighted Ovum

Hi ladies! I just found out on Wednesday that I have a blighted ovum. I am waiting for a D&C to be scheduled. I've already started some brown spotting. I'm really hoping I make it to get the D&C done, but in case I don't, I wanted to ask for miscarriage experiences. I'm 11 weeks along & was wondering what I should expect? I'm so nervous & scared to have a natural miscarriage. Anyone care to share your stories? Thank you!!!
