Implantation spotting?

I feel like I have experienced implantation spotting; yesterday I had discharge with a very slight pink tint, didn't notice any throughout the day, had some more very faint pink blood mixed with lots of discharge yesterday evening, and nothing again this morning. I was just wondering if this sounds similar to anyone else's experience? Is implantation spotting even common? And when/if you had implantation spotting how long after did you test and get a positive pregnancy test? Any advice/tips are helpful! Thanks everyone! 😊
