I would not be certain but t would be best to use another form of contraception for the rest of your cycle and possibly the one after just to be on the safe side. Antibiotics do not stop the pill working, but do lower its success rate to about 92%, for this reason another form of contraception is advisable.

You will need to use a back up method while you are taking the antibiotics and for one week after stopping them.
