Have you guys had really weird period changes?

usually my period would start around now but there's nothing at all! I'm not even spotting! I've also been producing less and less discharge which is worrying me a lot but i feel like it's been increasing.

my period symptoms have also increased a lot like cramps and cravings and digestive problems. I've been getting longer abdominal pain. They also usually last like 2 days but it's almost been 4 and no period yet. :( i'm not pregnant but has anyone else had this happen before?

i mean i guess it's hormonal changes and I've been pretty stressed lately. But idk

Is this normal for a 16 year old girl? My first period ever was when i was 10 years old.
