Implantation Bleeding?

Hi!

Any thoughts on if I could be having Implantation Bleeding? (See pic) I had pinkish spots when I wiped on the 6th and thought “great, I’ve gained weight so my period is coming a full week early.” I slipped on a tampon and thought nothing of it....THEN...it turned dark brown on the 7th....Again, only there when I wipe...today it’s barely anything. I “think” I feel like AF is coming...but I can’t tell and usually it’s obvious. AF isn’t due until Thursday....any thoughts?

Also, it’s been a awhile since I paid attention to TTC...I had to let is go for sanity purposes...so is IB even still considered a symptom?
