No sore boobs but i am pregnant

Kait

I am pregnant dark lines on all my hpt and doc confirmed today. I’m 4 weeks, i don’t really have sore boobs. They’re a little heavy but not insanely sore or enlarged. Is that ok??

Only other symptoms i have right now is some lower back pain, and lots of fatigue.

I’m probably over thinking but i miscarried in December so I’m just a little nervous.
