Help!

My cycles are always on time 26 to 27 days apart. Never been more than a day late. I was suppose to have started on the 13th of October, I didnt, however I felt real bloated and only one time going to the bathroom did I have spotting so I thought I was about to start. However it's Friday and I still haven't started and no more spotting nothing. I have been extremely tired and hungry more ofteb. Could I be pregnant and is it too soon to test?
