For those of you who experienced a natural miscarriage - Did you experience any symptoms or warning signs that the miscarriage is coming? For example, did you start spotting or have minor cramps, or did you suddenly get severe cramps and bleeding? I am waiting to miscarry after finding out earlier this week that I have a blighted ovum. The sac stopped growing three weeks ago and I am not showing any signs of miscarriage. The only recent change is that I am less bloated. I'm just curious if there are warning signs that miscarriage is starting. I might do a D & C if it seems to be taking too long. TIA!
