NERVOUS AF

So I will be 7 weeks on Tuesday so as of today I’m 6w5d . I’m super nervous because I can’t get my ultrasound until I’m 8 weeks but I don’t have an nausea at all! I’m honestly just tired with extremely sore boobs. Is it bad I don’t have nausea. I see other women with ultrasounds at 6 weeks. It’s my first pregnancy and so think I’m just extremely emotional and nervous.
