9DPO Brown Spotting?

I’m 9DPO with nothing out of the ordinary feeling, but when I went to the bathroom just now I noticed a small spot of brown in my undies. When I wiped, there was a tinge of pinkish brown, but a very small amount.

Period isn’t due for 6 more days and I’m quite regular, so it’s odd for me to be spotting so early.

Am I crazy, or could this be implantation bleeding? Maybe I’m just reading into it. 😕
