Don’t know what to do

I’m 16 and i’m on birth control but i started taking antibiotics and me and my boyfriend continued to have sex with him cumming in me because no one told me, not the doctors or anything. My mom said something by the time it was too late . i read that this certain antibiotic does lessen birth control and i don’t know what to do because my boyfriend would be so mad. I told him before i had baby fever so he would probably accuse me of doing it on purpose. But it wasn’t at all! I’ve always wanted to wait for marriage for a baby the baby fever is just something people say.. I’m so freaked out my life is gonna be over if i am

UPDATE- Not pregnant
