Is no symptoms a symptom??

So I’m only one day late for my period, which is pretty abnormal because my period is usually spot on every month. My SO and I use the pull out method and I’m not on birth control. I’ve had none of my usual PMS symptoms, no sore boobs, no cramping. I’ve had some lower back pain which I’ve never had before, I’ve been incredibly angry at everything, crazy mood swings, extremely tired. But not my usual PMS symptoms. I’m just paranoid and probably stressed. But has anyone experienced anything similar?
