Wierd

(Excuse the details) So I got my period at its normal time. But it’s been weird. I’ve only been using tampons and only one time have I had a fully covered tampon on the second day after wearing it overnight. The first day and everyday since, I have only the tip of the tampon have a little blood on it. Even earring it overnight, there’s barely blood on it in the morning. I usually have heavy and have to constantly change tampons. Am i just having a weirdly light period or should I be worried?
