7 weeks 4 days pregnant and no symptoms

Pari

I want to ask that I am 7 weeks 4 days pregnant but not a single symptom. Is it normal? My US appointment is on 17th Feb but no symptoms make me worried. Is anyone else have experience successful pregnancy without any symptom? This is my first pregnancy but had two early miscarriages in past. I am so worried to see that everyone is having symptoms, why I don't have any?
