Nervous and always worried. Advice?

Jessica

I am 11 + 3 and so nervous. I am so scared of a miscarriage all the time! How do you guys handle the worry? I saw baby at 8 + 3 and 9 + 4 and baby was right on track with a strong heartbeat (171/174). My dr doesn't seem concerned at all. I see her once a month now so I get reassurance every 4 weeks but its every day I don't see baby I worry. I just can't shake the fear of going in and not finding a heartbeat.
