5 days late

I looked at my insights and it said 5 days missed period. I’ve had light brown spotting like barely anything like two drops of discharge on my panties. I don’t think I’m pregnant, but if I am I’ll post it! I hope I am hehehe so yeah it may be implantation bleeding which occurs ten or so days after conception so if it is implantation bleeding I’m stoked, or just old blood getting ready for a period flow. Anyone else experienced implantation bleeding or has light brown discharge before a period ( this is a first). Also I’ve been super not hungry so I don’t think it’s pregnancy cause wouldn’t I be hungry all the time?
