Cycle or Pregnant?

I have had two days of morning sickness and nausea. I took a Clear Blue test and it said Not Pregnate. My period was supposed to start today and nothing yet. My belly feels bloated/swollen a little. I'm a little concerned and I don't know wether or it this is my normal period cycle or if I am pregnate. I was on the the pill (TriCyclen) three months ago and have been off this past month. Can anyone help?
