pregnancy

So I'm 16 and I just had sex with my boyrfriend twice over the weekend, once on Saturday and once on Sunday. Saturday was both of our first times....I was on my period kind of. I was bleeding on Thursday but it was very light and it's basically just been weird brown discharge. I'm on birth control for acne medication and he used a condom, but I'm still kind of paranoid that I may have gotten pregnant. Thoughts?
