Can Flucloxacillin And Microgynon Together Cause Any Problem?

Hi, i take microgynon 30 as a contraceptive, and today was prescribed a weeks course of flucloxacillin 500 for an infected cut i have on my leg. I have taken my first antibiotic dose today, which is the first pill-free day in my microgynon cycle... Do i need to use other contraceptives whilst i'm on my week's antibiotics? And for how long after i finish the course do i need to continue to use condoms? Thanks very much!
