I think I'm pregnant!!!

I'm 16. My last period was from June 6-12. Then on the 19th I had sex with my boyfriend without a condom and he came inside me, I'm in birth control pills but for 2 days in a row before we had sex I took the pills an 2 hours later then I normally do . Now I'm scared. I'm going to get a pregnancy test but I'm scared anyways. I need help!!!!
