Sex and Antibiotics

Is it true that antibiotics effect the pill drastically? I've been researching it and there is only one type of antibiotic that is proven to effect it. The antibiotic I was taking was not that one, and I had sex the day after I finished it and my SO came inside me (we were in the moment and came at the same time 😊) I'm not too worried but has anyone got any other experienxes or information? i take my pill at the same time everyday and haven't missed a pill.
