Signs your pregnancy is going well?

I’m 6.4 weeks pregnant, what can give me more assurance everything will be okay?

Only symptoms I have is breast are so sore, and I’m super tired a lot, and I’m also sometimes nauseated when I need to eat.

But I don’t have a dr appt until May 19th but I want to know other ways I can feel confident (knowing of course there could always be a chance of miscarrying)

Also, I read that a baby’s heart starts beating around this time, are there ways I can feel that? Like I don’t feel anything different and I feel like there should be a sign it is, but idk!! Ive only ever been pregnant once but it was a chemical at 4 weeks.
