i started taking the pill 21 days ago ( tomorrow will be my 21st active pill day) and i still have not started my period. i didnt do the first day of the period start nor the sunday start. my question is- when will i get my period? and if i dont get it in 2 days do i keep taking the green "inactive" pills if i dont have my period? or do i skip the green pills and start a new pack? also since it will be 21 days of taking the active pills am i technically now protected?
