I had been taking amoxicillin&clavulanic for about a week then 2 days after i stopped taking them i had sex. could this affect my bc(orto- tricycle)?

The Perils of Sex: Penicillins,which includes amoxicillin, can increase the metabolism of birth control pills because they induce the enzymes that chew them up and spit them out into the bile and urine.So can tetracyclines. The effect is not much, but more with the low-dose, like Ortho-Tri-Cyclen. I'd guess not much to worry,but I'm not you.Next time, use condoms until about 7 days after stopping the antibiotic
