Period 5 days late😭not sexually active

Normandy

My period is 5 days late! Im not pregnant. I have had some tenderness under my armpits usually that happens when I about to start but it never happened. Now its 5 days I do have like a white discharge which sometimes happens at the beginning of my cycle. But I have never made it past 5 days late. I have been stressing a little bit but I have gone they worse and still have had my period show up. Its just weird and its kinda stressing me out knowing my body is out of whack😭
