How Long After Starting Birth Control Are You Protected?
Most birth control methods provide protection within 7 days of starting, though timing varies by method. Combination birth control pills become effective after 7 consecutive days of use when started within the first 5 days of your menstrual cycle. If started at any other time, you need backup contraception for the first week. Progestin-only pills require 48 hours to become effective. The contraceptive patch and vaginal ring follow similar 7-day rules as combination pills. IUDs provide immediate protection when inserted, while the birth control shot (Depo-Provera) is effective immediately if given within the first 7 days of your period.
