4 days late

Tamia

Hi I’m just a little confused right now. My period is like clockwork I’m never this late. If I am ever late it’s usually like 1 days then I’ll get my period as normal for 5 days..

I am currently 4 days late including today tested yesterday and negative. Today I keep getting these brown cm things when I wipe and the last wipe I did kindve had a little pink but like hardly. Can anyone help pls 😭
