Hormonal Contraception: The Pill [General Discussion]
in Women's Health ·
I have a quick question. If I'm on birth control pills and had unprotected sex two days ago, but I'm supposed to start an antibiotic today—which I know can lower effectiveness—does that concern apply to the encounter from two days ago too, since sperm can live for up to five days? Or should I just not worry about the past encounter and focus on being extra careful during the antibiotic course and for seven days after?
