4 days late and no period

Abigayle

I am 4 days late and I still have not gotten my period I have never been late except when I was pregnant. I took a test this afternoon (not a fmu) and it was negative. I have my tubes tied and have been regular since then. Been dizzy on and off and yesterday had cramping on and off. Never experienced any pregnancy symptoms with my other pregnancies. Could i be late because of my tubes being tied or could I be pregnant.?
