Yes, needs to be: Consistent. If you are starting from scratch, begin Loestrin 24 Fe on day 1 of period or on 1st sunday after day 1. Use white tab x 24 days & then brown tab x 4 days. If you start on a sunday – use back up protection until you have taken the white pill x 7 straight days.

Depends on how late: If you are late by a day or two it will be ok for protection against pregnancy.But if you are late by several days than i will use alternate method for birth control. Birth control pills work by preventing ovulation and if ovulation has occurred you can get pregnant.
