4 days late and worried

I'm 4 day late and I'm experiencing much pain in my right pelvic, stretchy egg white mucus, sore nipples at touch, and to top it off, upper right thigh that is just crazy. I was going to the doctor because of the pain but I'll wait. I dont know if me waiting until tomorrow to see if my cycle would come since itll come on the 1st if not around the ending of the month. Any suggestions or possible answers to my concern?
