first miscarriages are so shocking...you never think it will happen to you...especially after healthy pregnancies. I am sorry you have to go through this. The earlier you miscarry the easier a natural one will be. Also, they tend to go easier if you go into an all out bleeding and progress to actually miscarrying right away verses spotting off and on for weeks or longer.
I had a D&C once for a miscarriage and it left me feeling sort of violated in a way. I had to have it in the hospital maternity ward. That was unpleasant and emotional. Then they knock you out and you wake up and everything is over and gone. I felt very robbed. However a few months ago I had another m/c and opted to do it natural. I had been having weeks of spotting before the miscarriage diagnosis, kept getting told everything would be ok. Well it was a horrible experience. I had massive bleeding when it finally came on. massive. I was passing clots larger than softballs continously and using bathroom towels instead of pads my bleeding was so bad. If anything like that starts happening go to ER right away. Its scary and painful.
Wishing you a speedy recovery physically and sending hugs. Its a painful thing and something you spend the rest of your life thinking about.
