Could it be early pregnancy signs

I need help figuring out what is going on, so on Thursday my glow calendar told me I had 4 days before my cycle starts which will be the 8th. Friday I started spotting an it was really light to the point it barely showed up on a pad and today is the same way I'm spotting it's light I haven't started bleeding heavy or anything it still don't show on a pad that im bleeding and there's no blood clots. Could it be implantation bleeding and should I test now or just wait and see if I miss my period?
