I had a scan last week at 9 weeks which showed the baby with a heartbeat and where it should be etc.. At the time I was ecstatic.
I'm 10 weeks now and still worrying that something is going to go wrong before I have my 12 week scan in March, like the baby's heart stopping and I have a missed miscarriage. 
Does anyone know how likely is it to have a miscarriage after seeing a heartbeat at 9 weeks?
