How Long Does It Take Birth Control To Work? | The Right Parenting

“You are pregnant!” This news can make women either jump with excitement or totally freak out. The most common rejoinder in the latter case is: “What? How? Why? But I was on birth control…” Most women get pregnant despite being on birth control, and cannot figure out where it went wrong. Besides many other factors that might have messed up, a common mistake is that they are not aware of “how long does it take birth control to work?”

Hence to avoid the unexpected pregnancy scare, you must know: How long are you not protected from pregnancy after starting a birth control method?

What factors determine the time for birth control to work?

“How long does it take birth control to work” depends on:

  • the method of birth control used
  • the time of the month you start using it
  • personal factors

Some methods start working immediately while others require some patience. You have to continue using backup methods like condoms until they are actually effective!

Do NOT panic! Let’s dive into each kind of birth control method separately.

The Pill

The pill is basically a hormone medication that tricks your body into believing that it is already pregnant and prevents the release of eggs from ovaries. Cunning, isn’t it? But it needs to maintain that state for a couple of weeks before ovulation for your body to adjust to the new status.

The pills are taken every day for 3 weeks followed by a placebo week in which dummy pills without hormones are taken. According to the Center for Disease Control and Prevention (CDC), the pill is 99.7% effective with perfect use but 92% with typical use.

The Combination Pill: How long does it take birth control to work?

The combination pill contains both estrogen and progesterone. If you start taking your combination pills within the first five days of your period, you are lucky! You can have sex right away. But if not, you have to wait for 7 days. If you want to have intercourse during that duration, use backup methods like condoms.

The Progestin-only Pill: How long does it take birth control to work?

If you are a lactating woman or are concerned about the side-effects of estrogen, you can take the mini-pill which contains only progesterone. It is not as effective as the combination pill in suppressing ovulation. However, it thickens cervical mucus to prevent sperms from reaching the eggs.

It will start producing its “contraceptive effect” effectively two days later, regardless of the time you start using the pill.

Caveats

  • This may be different for certain types of pills. Read the instructions on your pill carefully.
  • Do not miss the pill.
  • Take the pill at the same time every day.

If you miss the pill

  • If you have missed one pill, take the pill immediately when you remember, even if you have to take two pills in a day, and continue taking the pills normally. Fortunately, you are still protected from pregnancy; there is no need for extra contraception methods.
  • If you have missed 2 or more pills, take the pill immediately when you remember. But you should also use other contraceptive methods like condoms for 7 days in case of a combination pill and 2 days in case of progestin-only pill to be protected from pregnancy.

Intrauterine Devices (IUDs)

An intrauterine device or IUD is a reversible birth control method. It is a T-shaped device inserted in your uterus. There are two types of IUDs: Copper and Hormonal IUDs. Both of them cause the release of chemicals that kill sperms by causing an inflammation reaction. However hormonal IUDs also release progesterone that thickens cervical mucus and prevents the uterine lining thickening.

An IUD needs to be replaced after 3 to 10 years. They are 99% effective if checked for correct placement.

Birth Control Methods for Men

70% of all contraceptives are used by women. However, some women are not able to use contraceptives due to health conditions or side effects.

Nevertheless, scientists are making resurgent efforts to find novel contraceptives for men.
