Missed miscarriage advice...

Heidi

So i went for a scan last week, i shouldve been 9 weeks, baby measured 6 with no heartbeat, she struggled to.find it due to a retroverted uterus? its now been 3.5weeks since the baby stopped growing and no signs of passing it yet. My 3yo keeps telling me there was supposed to be 2 babies. Is it at all possible there is a second one in there that we didnt spot? Im still having symtoms and no cramping, bleeding etc...Does anyone have any positive stories?If not what are peoples experiences with a D&C? Would you recommend, how long after were you able to start TTC again?
