It does take at least 7 days for the birth control pill to be effective. However, if you started your pills during your period (on Thursday), and had sex the following Sunday, your risk of pregnancy would be very low.
Continue taking your pills consistently & correctly. If you do not get a period during your placebo (sugar) pill week, you may want to do a pregnancy test, either at home or our clinic, for peace of mind.
