You may want to schedule an appointment with your doctor for a blood test, they are much more accurate.

Are you dealing with any stress? This can cause late periods.

No I'm not stressed.guess I'll wait till Monday then call my doctor if nothing happens by then

I would do that if I were you. I hope you get the answers you want. Please keep me posted.
