Unusual AF this month

So this month my period was very strange and I was wondering if anyone has experienced the same and if it maybe meant anything. So my period was a week early, which it NEVER is, I have always been very regular. It also only lasted for like a day and a half, which usually it will last for about 4-5 days. And I only had to use like 3 tampons and a few pads which usually I go through almost a box each month. Is it normal to have an unusual period like this out of nowhere?
