Could I be pregnant?

OKAY. So I'm currently 5 days late for my period to start, I've never been this late before. But me and my Husband didnt have sex until the 24th (which is a non fertile day). I've been spotting on and off and the only symptoms I've been having are breast tenderness & slightly heavier breasts. I'll be making an appointment with my Dr in a week or so if my period doesn't show. Any opinions?
