Barely a Period

So I'm on the pill and take the sugar pills when my period is projected to start and it started right on time but it was crazy light (like just spotting) the whole time. It got lighter when I started the pill a year ago but this is the lightest its ever been. After reading up on it I'm pretty certain everything's fine and it was just a really light period (we'll see what happens next month), I just wanted to know if anyone else has experienced this
