Wtf is this!?! TMI picture warming!!

My period isn’t due till Wednesday but last night I had 3 or 4 tony spots of light brown. I just assumed it was old blood and I was spotting before my period, maybe getting my period early even tho I have never been early or had brown blood before. Last night and this morning I also had slightly light brown discharge when I wiped after peeing. I put a tampon in this morning just in case, thinking I was still just going to be starting my period early. But I haven’t felt it yet so I just took my tampon out and... what the fuck is this!?!? It’s dark brown blood almost? I’ve never seen this color come out of my body though has anyone had this? Freaked me out to see this. Help!!! My blood of my periods has always been bright red I am so lost right now
