Brown spotting before period

So usually I’ll get brown spotting that’s pretty medium ish 5 days before period that gradually gets heavier and turns into my period. This period. 4 days before I got light brown spotting for a few hours this happened for the past 3 days. Is that normal? Today is the day before my period and I haven’t had any spotting at all. I’ve been trying to have a baby but I don’t remember implantation bleeding being like this at all. Anyone experience this?
