Im going to reeding music festival next week so was planning to go strate on to next pack of contraseptive pill tommorrow and miss a period but been on antibiotics since wed and finish the course next wed. Will my period still come even if I keep taking the pill because of the antibiotics (phenoxymethlpenicillin). Or should I just not take the pill for the week and hope my period has stoped before I get to the festival. Thanks for any input, x
