Does Taking Antibiotics While On Birth Control Cause Pregnancy?

Hi :)
uhm, so i've had sex 3 times this month, twice with condoms, but with or without a condom no one ever.. came... in me. Im on the birth control pill. I have to take antibiotics for a urinary tract infection, but if i take them could they like.... make me pregnant ? and also will my period come late even though im on the pill ? im sorry im soo all over the place. Thank you !
