odd spotting

This isn’t a post being like oh tell me I’m pregnant just saying that before I begin.

I was spotting at 5 DPO, 8 DPO, and 11 DPO. Then at 12 DPO, I started my period 4-6 days early (i am between 24 and 26 day cycles). I’ve been just spotting brown stuff, which I’m assuming is my period, but it’s getting lighter and lighter with each day. All negative tests, and it’s almost a discharge with a little spotting now. It’s only been two days with this. Anyone else? It’s my first cycle off BC so I’m attributing the weirdness of it to that, but I still want to know.
