Super early and quite heavy

Sofia

My period came super early, like a week and a couple days. When I first saw the blood is was pretty brown, which was weird. But then the next day, which is today, it got super heavy. I don’t think I have had a period this heavy. I’m in a bit of a tough spot as I have midterms and I won’t be able to leave in the middle of the class to change. I wore black sweatpants just in case. Is this normal I guess?
