Have any of you ladies ever had implantation bleeding a few days before your period? And was it like a brown discharge?

I’m asking because yesterday I felt like my period was coming on and towards the end of the day when I wiped I would see brown, also I put a tampon in and when i take it out it was brown discharge but not a flow & no sign of red blood. As of today I have nothing. My period is supposed to start in 2 more days.
