Implantation bleeding or early period?

[iGotADilemma]

So I'm about 13dpo today and yesterday I had dark brown spotting which usually signifies the start of my period, except it stopped after a while and turned light pink when I wiped. I put on a pad which has been empty ever since. If this is my period then it's 4 days early which usually never happens. Also did a few pregnancy tests in the last couple of days which have all been negative. Am I definitely out this month or could this be some type of implantation bleed? Did anyone experience similar and then go on to get a BFP?

Sounds like it could be implantation bleeding to me. Mine was similar - brown and then pink, very light.

Were you testing negative before the implantation bleed?

I wasn't ttc then so can't really remember but I did take a couple tests and they were negative, and then tested positive maybe a few days/week later

Very possibly implantation bleeding, sounds very similar to mine.
I just tried to put it out my head as much as possible and did a test a week later. It was very faint so I think if I'd tested earlier it would have been negative.
