Brown CM

So Glow says my period was meant to start 5 days ago. My cycle is pretty irregular so I don’t want to get my hopes up yet but the last 2 days I have had slight brown spotting in my undies. I have been off the pill for 11 months and this has never happened before. I have also been getting a hot tingly feeling in my cheeks for the past 2 weeks. Has anyone else had these symptoms?
