Terrified of all that could go wrong(

I'm only 4w4d today. We were trying for 7 months and are very happy. I'm happy about the symptoms, but now I'm so so scared of misscariage or blighted ovum. It keeps me awake at night. My doctor won't see me and won't do the ultrasound until thaw end of the 1st trimester unless there is something obviously wrong (like bleeding or severe cramping). How do you cope with being scared? What do you do?
