Is this normal or should I be worried?

Hello

I discovered a strange discharge in my panties today.

I had my period at the beginning of the month and now there is this very sticky, transparent discharge with brown tissue or something like that, it's hard to describe!

I'm sending a picture so you can see it better (I apologize in advance if it's gross or something like that)

Is this normal? I've never had anything like this happen before, and I'm already a little worried.

thank you in advance!
