Is it normal to have discharge a lot during periods?

Like this

I had that in my second day but it was soaked with blood and the third day was just brown spotting nothing else.

I also had that in the beginning of my last cycle and the last day so. I'm confused because I have never experience discharge during periods especially this time it happened on my cycle day 2?

What could be causing it? Ill definitely be going to my doctor soon to ask about it.
