So nervous!!! In need of reassurance

Becca • ✨✨Mother of 2 ✨✨
I am 5 weeks and 2 days today, my first appointment is on the 11 of nov I'll be 8 weeks! I am so nervous because I barely have symptoms I know that can be normal but everyone I talk to has some sort of symptom. I am nervous for my ultrasound I'm scarred they aren't going to find the baby or the heart beat! Am I just being stupid and causing stress that I don't need, or is it normal to have these fears? :(
