Anything to be concerned about??? Please help

K

Okay, so I just found out Sunday I’m pregnant, I had four clearly positives tests, my first doctor appointment is Monday morning, and I’m estimating that I’m about four weeks. This morning after I peed when I got out of the shower, I had some light brown discharge when I wiped, I didn’t have anything in my panties before the shower though. Anything to be concerned about?? I’m going to attach pictures (sorry if tmi), I really just need some reassurance about if it’s anything to worry or not until I have my appointment on Monday. Thanks!

There’s no pink/red in it, just light brown.
