I Am 5 Days Late (normally My Period Would Be

I am 5 days late (normally my period would be off 3 days & I've experienced a whole month of no period) since my predicted due date for my period. Occasionally I would feel a slight cramp or pinch then it'll go away within a few seconds. I don't believe I'm experiencing anything different other than not experiencing any type of the typical symptoms prior to my period starting like I usually would which is sore breasts, cramping, mood swings. Could I be pregnant?
