Hi, I am on the pill, marvelon and I havent

Patient: Hi, I am on the pill, marvelon and I havent missed any, however i was perscribed trimthoprin for a UTI today (Tuesday) and my doctor told me to use extra protection during and a week after my course. I was wondering if I am still protected by the pill for intercourse that happened on Saturday, so 3 days before?Thank you

Doctor:
