I can't tell if my period is normal

I've been on the pill for three months, last month I hadn't started the sugar pills yet and I was spotting/bleeding for two weeks and now this month I'm on day 3 of the sugar pills and I'm experiencing a couple drops of light blood, barely anything. I don't think I'm pregnant cause I make my boyfriend use a condom and pull out. I'm just concerned about this not being normal...
