Common Birth Control Myths & What You Really Need to Know

Written by Favour Obioha

Birth control is one of the most effective ways to prevent unintended pregnancies and manage reproductive health, but despite its widespread use, misconceptions and myths still persist. Misinformation about contraceptives can lead to unnecessary fear, incorrect use, or even avoiding birth control altogether.

In this article, we’ll debunk common birth control myths and provide factual, science-backed information to help you make informed decisions about your reproductive health.

Myth #1: Birth Control Causes Infertility

The Truth: Birth control does NOT cause infertility.

Many women worry that using hormonal contraceptives like the pill, IUD, or implants will affect their ability to conceive in the future. The reality is that once you stop using birth control, your fertility returns to normal.

What happens when you stop birth control?

  • Combination pills & patches: Ovulation resumes within one to three months.

  • IUDs & implants: Fertility returns immediately after removal.

  • Injectable contraceptives (e.g., Depo-Provera): It may take 6-12 months for fertility to fully return.

Fact: Birth control helps regulate menstrual cycles, which can even improve fertility in women with irregular periods.

Myth #2: The Pill is the Only Effective Form of Birth Control

The Truth: There are multiple highly effective contraceptive options.

While the birth control pill is one of the most well-known contraceptives, other methods may be more effective depending on your needs.

1. Long-Acting Reversible Contraceptives (LARCs):

  • IUDs (Hormonal & Copper): Over 99% effective and lasts 3-10 years.

  • Birth Control Implant (Nexplanon): Over 99% effective and lasts up to 3 years.

2. Short-Term Options:

  • The Patch & Ring: 91-99% effective.

  • The Shot (Depo-Provera): 94-99% effective.

3. Barrier Methods (Used During Sex):

  • Male/Female Condoms: About 85-98% effective when used correctly.

  • Diaphragm & Cervical Cap: About 71-88% effective.

Fact: IUDs and implants are among the most effective birth control methods, yet they are underutilized due to misconceptions.

Myth #3: Birth Control Pills Cause Weight Gain

The Truth: Most women do NOT experience significant weight gain on the pill.

Many women worry that taking hormonal contraceptives will lead to weight gain, but research shows that only some women experience mild fluid retention, and this effect is usually temporary.

What the science says:

  • A review by the Cochrane Library found no consistent evidence linking birth control pills to long-term weight gain.

  • Depo-Provera (the shot) is the only method linked to possible weight gain over time, but this varies between individuals.

Fact: If you’re concerned about weight changes, talk to your healthcare provider about low-dose hormonal options or non-hormonal methods.

Myth #4: You Need to Take a Break from Birth Control to "Cleanse" Your Body

The Truth: No break is needed—long-term use is safe.

Some believe that taking birth control for too long “builds up” hormones in the body or causes toxic side effects. In reality, modern birth control methods are designed for continuous use without harming fertility or health.

Why no break is needed:

  • Hormonal birth control does not accumulate in the body—it leaves your system within days once you stop taking it.

  • There is no medical reason to take a break unless you’re experiencing side effects or planning to conceive.

Fact: Taking breaks can actually increase your risk of pregnancy, so it’s best to continue as prescribed.

Myth #5: The Morning-After Pill is the Same as an Abortion Pill

The Truth: Emergency contraception prevents pregnancy—it does not terminate it.

Many confuse the morning-after pill (Plan B, Postpill, Ella, etc.) with the abortion pill (Mifepristone & Misoprostol). They work in completely different ways:

1. Morning-After Pill:

  • Prevents ovulation before fertilization happens.

  • Works best within 24 hours (but can be effective up to 5 days).

2. Abortion Pill:

  • Ends an existing pregnancy by blocking pregnancy hormones.

  • Can only be used under medical supervision within 10 weeks of pregnancy.

Fact: Emergency contraception is NOT an abortion pill—it’s a safe and effective backup option to prevent pregnancy after unprotected sex.

Myth #6: If You Don't Have Sex Often, You Don't Need Birth Control

The Truth: Pregnancy can happen even if you have sex once in a while.

Many people assume that because they rarely have sex, they don’t need a reliable birth control method. However, it only takes ONE unprotected encounter to get pregnant.

Better options for occasional use:

  • Condoms (with emergency contraception as a backup).

  • The copper IUD (can be used for both emergency & long-term birth control).

  • Progestin-only pills or patches for flexible, short-term use.

Fact: If you’re sexually active at all, it’s best to have a consistent birth control plan.

Myth #7: Birth Control is Only for Young Women

The Truth: Women over 35 can safely use birth control, too!

Some people believe that after a certain age, birth control is unnecessary. However, women remain fertile until menopause (typically around age 50-55).

Best birth control options for women over 35:

  • IUDs (hormonal or copper) – Safe and highly effective.

  • Mini-pills (progestin-only pills) – Good for women at risk of blood clots.

  • Permanent options like tubal ligation or vasectomy for partners.

Fact: If you’re not ready for pregnancy, you still need protection—even in your late 30s and 40s.

Final Thoughts

Understanding the truth about birth control empowers you to make the best decision for your health and lifestyle. Whether you prefer hormonal, non-hormonal, long-term, or short-term methods, there is a safe and effective option for everyone.

Key Takeaways:

  • Birth control does NOT cause infertility.

  • There are many options beyond the pill (IUDs, implants, patches, etc.).

  • There is no need to "cleanse" or take breaks from birth control.

  • Emergency contraception is NOT an abortion pill.

  • Women of ALL ages can benefit from contraception.
