How long does your period last?

Ni

I’m curious to know because I realized on my calendar on the app today this is my 8th day on my period. Sometimes mine lasts up to 10 days!! Does anyone else have long periods like this?

The app said I had a 7% chance of pregnancy today and it was the first day of my fertile week. Until I added that I still had AF🙄🤷🏼‍♀️😭
