Boob pain in early pregnancy

So this might be a dumb question.

I’m 4w2d pregnant. Is it normal to have the pain/tenderness in my boobs fluctuate? I’ve had breast pain since ovulation. Some days the pain/tenderness is really bad. Other days it’s not as awful.

Is this normal? Anyone else experience this? When did the pain lessen for you?

Of course I’m terrified of miscarriage and any little change in my symptoms scares me!
