Original: If started at any other time in the menstrual cycle , COCPs provide effective contraception only after 7 consecutive days use of active pills , so a backup method of contraception must be used until active pills have been taken for 7 consecutive days .
Simplified: If the treatment is started at any other time in the menstrual cycle , COCPs can not provide a safe means of contraception for the first 7 days of use .
