Should I be concerened?

Shyanne

So usually my periods start at the same time every month this one was late and it's but like it doesn't look or feel like I'm on my period. It's really light but the color is dark, like it's the color (I don't know of everybody's is like this) but at the end of my period it looks like a dirt dark black color and that's what it's looking like right now. I don't know what like is going on, if it's something I should be worried about or not?
