Implantation?

Yesterday I believe I was about 11dpo. I had spotting a few times throughout the day. The first time looked like older blood (brown tint) mixed in with my cervical mucous. The second time was a brighter pink color and I only saw it once when I wiped. I’ve had the wet feeling that makes me think AF is due literally any second for about 4-5 days now. But today again I do not have any sort of spotting whatsoever. I tested last night but BFN. Has anyone experienced anything similar to this??
