Who actually gets implantation bleeding?

Man I thought I sharted or something bc I had a little bit of brown in my panties 🤦🏼‍♀️ but I was so shocked because I feel like I would have noticed it as it happened I’m not decrepit. I never had runny BMs and could trust any fart so I just found that to be strange, like, who shit in my pants? And even more TMI but I just wiped at my b hole and it was clean and, you know didn’t feel dirty and this was right before my shower. I’m sure, certain in fact, that If that had happened I would have had a fussy brown eye.

Anyways I just took the L and moved on. Well the next day (today) I noticed at the end of the day a light brown tinge just all thru my pannies. A very little bit but it reminds me of the end of periods when you’re “browning”. I think maybe this could be implantation?
