Brown period blood?


Hi, the last time I had my period was at the beginning of February. It is just now starting today, 4/22. So far, I have only had brown blood, come out of me. And it is super light. My typical periods are super heavy on the first day with bright red blood. I know that means it’s old, but is this something I should worry about? I don’t think this is something to worry about but idk
