Hi good day i been on birth control novynette (21 pack) for years now but i think i been taking it wrong, after i finish a pack my period comes after 3 days for 6 days and i start my new pack on the 6th day, but it says i'm suppose to start each new pack on the 8th day, but if i do that it will be more than a week i will be without the pills, is my period supposed to come the day after the 21 days?? and then i start back on the 8th day after my period??? if so how do i do that will i have to go a month without taking the pills and start over??.......one last thing i lost a pill this month a took the last pill in the pack as replacement so i only have 20 will my period be a day earlier????
