Scared of 2nd Missed Miscarriage

Hey ladies, struggling a bit emotionally at the moment. I got married 2 years ago when I was 35, but we didn't start trying for a baby until I was 36. We got our BFP and we were excited. However, at 10 + 1 I had some spotting, paid for a private ultrasound at 10 + 4 and found out we had had a missed miscarriage. The baby had died at 6.5 weeks. We were devestated, but eager to try again. I'm currently 10 + 3 and there is no overt problems as yet. In fact, there are more symptoms with this pregnancy than I had with my first. Nevertheless, the closer I get to my ultrasound date (30 November), the more anxious I become. I can't bear the thought of going to the ultrasound and finding out the worst again. I keep replaying what happened the first time around. I'm just so scared of having another missed miscarriage. Any words of advice/wisdom much appreciated.
