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.
