I seriously, seriously don't think you're pregnant. And the reasons that I say that is because, 1) you're on birth control and taking it correctly, 2) you didn't have sex at the usual most fertile time of the cycle, 3) you got your period.

Being on birth control can cause your period to be lighter. In fact, the reason that a lot of people go on birth control in the first place isn't necessarily to prevent pregnancy, but to make their periods lighter and more manageable. It also helps with cramps.

I really, really do not think that you have anything to worry about. I was on birth control for almost a year and had sex regularly without even having him pull out or use any other form of birth control and never got pregnant while doing that.
