ok... I need help

Trinity

Okay earlier (about 5 hours ago) I had some cramps that felt like menstrual cramps and I was bleeding so I put on a panty liner instead of a full Pad( which was still clean). I just used the bathroom and now it's a very light pink that I wiped from myself... probably brown now. It's five days earlier than my period is supposed to show 😔 what's could be going on?
