Possible pregnancy

Has anyone ever experienced all the signs of pregnancy a week after their period? I have had dizziness, hot flashes, nausea, cramps, am emotional, back pain, and breast changes including changing of color, swelling, and tenderness. My normal periods are normally 42-44 days apart but with my last one I only had about 28 days apart. I plan to take a test tomorrow morning which would be 6 days before my next period is scheduled. Did anyone have this? We’re you in fact pregnant or was your body just playing games on you? I have had one baby and so far this is completely different than when I found out I was pregnant with my daughter. Any advise helps!
