late period?

Ar
okay so last night i got some pretty minor cramps and i figured its because I'm supposed to start my period today and when i woke up in the morning there was nothing, no spotting or anything and i felt completely fine, I'm a little worried to see why this is since it's never happened before, my periods always start early in the morning so I'm just concerned a bit ? idk if I'm being a little over dramatic or whatever
