Period is later than its been in two years

So for the past two years my period has always come between days 24-26. Today is day 26 and im getting extremely mild cramping in my lower back and inner thighs, but no sign of a period? I know its normal to be a few days late, but has this happened to anyone else too? Like your period has always come like clockwork and was late for no reason? Or were you pregnant? I know it could still come but im looking for some experiences as well.

Thanks for answering 😊
