Period?

Mariah

So I thought I started my period today, but now I don’t really know now. I wiped earlier and it was pink and light brown so I figured I started. After a few hours when I went to the bathroom there was barely anything and again a few hours later. I’ve been cramping the past few days and I’m not supposed to start for another 6 days. Don’t get me wrong I hope it’s my period starting now but it’s weird for me to not start heavy. Anyone else have this?
