Implantation?

A little history, DH and I had sex on the two most fertile days according to Glow. We weren't ttc this time around because baby would be due the time of our out of state move.

Well, this past week I've been spoting, its light and a dark brown color.. . I have no other symptoms, but I've been very grumpy-I'm plying this off on the fact that I haven't been eating until lunch for some reason.

Anyway, does this timeline add up to implantation bleeding? I was talking to some friends and they both looked at me like I was crazy

AF should arrive 10/14
