Light spotting and cramping period due on 5/31

Hey guys so this is me trying for the second baby. First baby took a year and when I got pregnant with her I had super light spotting a few days before my period. If u were not looking I would have missed the spotting. I had the same thing today. I'm hoping it's not my period coming on but I have had zero spotting since the one little dot in the am. Anyone in the same boat?
