Implantatiom bleeding?

This isn't my photo as I didn't have my phone on me at work.

Had something very similar maybe slightly lighter. Been having creamy discharge for a few days as well.

Start of AF? Or is it a sign?

Boobs feel heavy and sore. Cramping appt and feel a bit sick and icky. Took a test two days ago but it was negative.
