Bleeding

So it’s been 4 days of missed period. I’ve been having light pink spotting and I only have it when I wipe. It’s way too light to be my period. I’ve never even had this before. Anyone know what it could be? I also took a test but people say not to take the rexall one step brand but it looks positive to me. Please don’t be rude on here. I just need alittle help because I didn’t have this with either of my kids.
