Negative tests but all of the symptoms!

I swear, you would think I was pregnant if I told you everything I'm going through! Extremely sore breasts, nausea (at night), cramping, headache, dizzyness....but all negative tests! We have been TTC, so I am not trying to get anxious. I'm supposed to start my menstrual cycle today or tomorrow. So, should I wait and see if I start, or go to the doctor? Am I jumping to conclusions?(Just got sick like half hour. Sorry TMI)
