How long does it take for birth control pills to be effective?

Question

I started taking the pills 2 weeks after I had my baby. Will it take the full month to become effective?

Answer 1

depends on which pill... there are a few different doses...

Your clinician will explain when you should start taking the pill. Taking the pill at the same time each day makes it more effective — pick a time of day that is easy to remember.

If you start the combination pill within five days after the start of your period, take the first active pill of the first pack. You will not need to use a back up method of birth control. You are protected against pregnancy immediately.

If you start the combination pill at any other time during your menstrual cycle, take the first active pill of the first pack. Use another method of birth control if you have vaginal intercourse during the first week of combination pill use — protection will begin after seven days.

You may start the progestin-only pill at any time. Use another method of birth control if you have vaginal intercourse during the first 48 hours of progestin-pill use — protection will begin after two days.

Taking the progestin-only pill at the same time each day is essential — if you take it more than three hours past the regular time, you need to use a back up method of birth control for 48 hours after taking the late pill.

Oh, yes, in fact you should use alternate protection for a full month after your first regular menstruation after the lochia (bloody discharge after giving birth) ends. BTW, congrats!
