Implantation bleeding?

Hi ladies. I am currently 2 days late. AF has yet to show any REAL signs. I mean, I’m tired, moody, boobs aren’t sore anymore, however they have huge veins in the areolas, but I’ve had zero “period” cramps. Now, I was driving this morning and felt this rush of “fluid”. I got home and wiped and the lightest of pink was left on the toilet paper. I took a test last Saturday that ended up showing a VERY faint line, but all others after that have been negative. Now that I have had this spotting, I’m starting to notice some cramping, but it isn’t unbearable.

So my question is, has anyone else experienced this and gotten a BFP within the days to come? Or should I just expect AF? 😐
