Miscarriage nightmares...

Trena
Ugh. I'm 11w3d, I tried to get pregnant for 5 years, I've had 3 miscarriages, none of my previous pregnancies lasted to 8 weeks.
I had a nightmare last night that I went to the doctor for an ultrasound and it showed no heartbeat and that the baby stopped growing at ten weeks.
When I woke up, I was so so upset. I haven't had any signs of miscarriage, and my next appointment isn't until the 8th.
I'm so worried. I don't know what I'd do if I lost this little one...
