Implantation bleeding

Melissa

With all 4 of my kids I recall having implantation bleeding and I'm thinking it might have happen again.

How long after implantation bleeding will (if you are) a positive show up?

Note: I had in the implant BC for 2 years. Had it removed 4-5 months ago. My periods have been relatively regular with no between bleeding. A couple days ago I have about 2 days of VERY light spotting that was bright pink and orange-ish.

Ideas!?
