Oh, sweetie, I am sorry to see you worrying about this. It is hard enough to go through... From my experience with a missed m/c (in Dec), it was very very clear, even to me, an untrained observer, that there was no heartbeat on the u/s. That little flicker?? Wasn't there. When the sono tech turned on the sound (and graph), there was nothing, no whoosh, just a flat line.
I didnt' ask for a second sono b/c I knew there was no need. :(
Don't worry, I'm sure they make VERY certain before recommending a d&c. Enjoy the little one you're expecting, and know that his/her brother/sister is in heaven.
My last baby, Cooper, was a "rainbow baby"-- a baby who wouldn't have been born if not for a previous m/c-- and I look at him every day and know that HE was the one I was meant to have. Don't know why, and I still miss and cry for the others (I've lost 3), but some things we aren't meant to understand. ((hugs))
I don't think that the D&C was a bad move. If the u/s did not detect a hb then the fetus had likely passed. Absence of cardiac activity indicates fetal demise. I am so sorry and I know how you feel, but you did the right thing so now you may recover and move forward. Don't second guess yourself. Most OBs would never risk a D&C if they weren't 100% sure.
Good luck to you.
Bless your heart. A sono is used to confirm fetal demise. You could have done this naturally (could have taken several days to couple of weeks to do on your own) and still ended up with a D&C because sometimes miscarriages bleed too much. You did what your dr. felt was safest for you. I have learned over the years that bad things happen to really good people. Doesn't seem fair. Get yourself back to good health. This was not your fault! Unfortunately and sadly this happens.
