Light and really short period

I started my period the day I was supposed to start it but it was pretty light and I’ve only had a light period for like 2-3 days and it has seemed to stop. The day my period started, I went for a really intense run so idk if that had a factor in it?

**My periods usually last 5ish days and I usually have one or two really heavy days & my flow has been the usual color, enough to fill a pad with some clots
