Breast tenderness wayyy before period...normal?

So I have had 5 solid days of really heavy and tender breasts. I'm a week away from my period and the app states that if I have more than 5 days of tenderness more than a week away, I should be evaluated. Anyone ever experience this? Should I bother with the dr? Might just wait to see when (and if) I get my period and if it subsides. I have a gyn appt in 3 weeks so I don't want to go in earlier if necessary! Thanks for any/all input :)
