First scan in a few hours and TERRIFIED something will be wrong

I had an early mc last year, had a profound effect on me and really changed me as a person. Now I’m 7 + 5 weeks and have my viability scan in a few hours. Feel sick to my stomach something is wrong, don’t know if it is intuition or fear because of the previous loss. My first pregnancy I knew the entire way through everything was fine, I just felt it

UPDATE: all ok, abdominal us and saw Heart beat flickering. Measuring a week behind but I expected that as I ovulate very late and knew already. Such a relief 😊
