I should relax right?

I’m constantly paranoid about miscarriage. We saw our baby on ultrasound right around 6 weeks with a heart beat and in the correct spot. However I’m still so nervous. I’ve had very few symptoms. Sore breasts off and on and occasional nausea but aside from that I don’t feel any different. I haven’t had any spotting or cramping so I need to relax right? I’ve read that the chance of miscarriage is small at this point but I just wish there was a way to know everything is okay.
