Implantation Bleeding? -UPDATE

So 7 days before my period I went to the toilet, wiped, and there was a bit of light pink blood on the toilet paper and then that was it? One wipe, it was gone and never came back? My period is due today or within at least the next couple days and we are in the 3rd cycle ttc, could that have been IB? Or am I thinking about it too much? I’ve also done a test 2 days ago and it was negative.

Upadate - I got my period today :(
