has anyone experienced this???,

So last month my period was two days early. Normally it would last up to 7 days well this time it lasted 2& half days! It wasn't red like normal it was brown and very light. This month I am now 8 day late with no signs of my period coming. I am thinking it's late because I have flu. I have not tested yet. What do you think?  Please reply 🙏🏼🙏🏼🙏🏼
