hi so do we take it she was on top? if so then i don't think you have a problem but some high strength antibiotics do reduce the effectiveness of bc pills. but please to stop your worries do use plan b if this was within the last 72 hours its called piece of mind. do hope this helps you. good luck
if we cont to have sex with a used condom for a few strokes and some cum leaked out the bottom on my hip is she pregnant. the condom didn't break i made sure by doing the water test. and she has been on birth control but has been on antibiotics for a week. then stopped taking the antibiotics 2-3 days before our sex. should i get plan b?
