Worry or no?

I’m 7 weeks tomorrow and my boobs feel heavier and dark but they aren’t getting firm and don’t hurt as much unless some pressure is applied. I have a doctor appointment in two weeks and am going talk to her about it but is this something I should be worried about or concerned?

I’ve had four miscarriages in the past. Two of them last year. I’m trying to relax and not stress to much about details and symptoms but it’s hard to put those feelings aside, I’m nervous with this pregnancy and praying this one stays.

Any helpful comments or suggestions would be very appreciated.
