Birth Control Advice: please help?

I was playing around with my boyfriend and he ejaculated on me, between the legs. The thing is, I have been taking the birth control pills for about 3 months almost 4, but I am currently on the second day of my period. For those who know about birth control, that means I am taking the light green pills, not the light blue pills (depending on the brand, it may be different colors). Is it possible for me with these variables involved to get pregnant?
