Negative but no period

My periods are never late sometimes early but never late! I took a pregnancy test lastnight and it was negative, I'm late by three days I'm not understanding at all I usually have period symptoms atleast a week before starting like acne & sore legs but I have no acne my face is clear and my skin looks healthier and my legs are fine. I've had some cramps by my belly button and intense sore boobs and I'm craving vanilla ice cream and I barely even eat ice cream! When should I test again?
