Starting OCP's

Describe the 3 methods and when backup protection is needed:

 

Definition
  • First-day start—the OC can be started on the first day of menses. When the OC is begun within the first 5 days after a period begins, contraceptive protection begins immediately and use of a back-up method is not necessary.
  • Sunday start— the first OC tablet is taken on the first Sunday following the beginning of menses. A back-up method of contraception should be used for the first 7 days the OC is taken when beginning the OC with a Sunday start.
  • Immediate Use—the OC can be started at any time after a negative pregnancy test. If the OC is started mid-cycle vs. during days 1–7 (the first week) of the cycle then a back-up method of contraception should be used for 7 days.
