Irregular period

Virginia

So my period always starts around these couple days. The first day is always the worst nonstop bleeding, cramping, feeling miserable. Then it slows down and last 6 days. My period has always been regular like that for me, but I’ve spotted maybe twice all day for my first day period. And it seems to be like the end of the period type of blood. This isn’t normal for my body to do this (at least for me). Should I maybe call my doctor or wait it out? Any ideas on causes for it being opposite?
