Birth control is a powerful tool, but no method is 100% foolproof. And if you’re here, you’re already doing the right thing: seeking answers without guilt. Even with the best intentions and habits, things can go sideways. And that’s not a reflection of your worth or responsibility, it’s a reminder that you still have choices, even in uncertain moments.
This blog will walk you through:
- How effective birth control really is.
- Why pregnancy can still happen (it’s not your fault!).
- What to do next if you’re worried.
- How to reclaim your peace of mind.
So if you have ever been in the situation or have been thinking, “Can you still get pregnant on birth control?” we are here to help you out. Let us have 'the talk' about what goes behind the scenes to help you prepare for the times ahead.
How Effective Are Different Birth Control Methods?
To ease your anxiety, let's start with numbers. Birth control is incredibly effective, but no contraceptive method is 100% foolproof.
- Implants & IUDs (99% effective): Once in the correct place, these require little effort and are the best at preventing pregnancy.
- Birth Control Pills (91-99% effective): The range depends on the right use vs. typical use. Missing a pill or taking it late reduces its effectiveness.
- Condoms (85% effective) are the usual go-to, and in most cases, they are better than nothing, but they are not as reliable as hormonal methods.
- Withdrawal (“pull-out method”) (78% effective): A risky business where timing and self-control are the key.

Key takeaway: “Typical use” accounts for human error (like forgetting a pill), while “perfect use” is under ideal conditions. Modern contraceptives are good when used correctly, but life happens to the best of us.
Reasons You Can Get Pregnant on Birth Control
Let’s normalise this: Pregnancy on birth control is rare but possible. Even the best birth control methods have failure rates, and here’s why:
- Missing Pills or Taking Them Late: Consistency is the way to go with birth control pills. You need to take them at the same time every day. If you forget a pill, even for a few hours, it can decrease its effectiveness.
- Medication Interactions: Mixing medicines might not serve you well, as some antibiotics, anti-seizure medications, and even herbal supplements can interfere with hormonal birth control.
- Vomiting or Diarrhoea: If you throw up shortly after taking your pill, your body might not absorb it properly.
- Incorrect IUD Placement: While it is not as common, an IUD can shift out of place, making it less effective.
- Using Expired or Damaged Condoms: A broken condom can lead to an unplanned pregnancy.
Most importantly, this is not a reflection of your responsibility or worth. Bodies are complex, and birth control is a partnership between you and science, not a test you can “fail.”
Birth Control and Your Autonomy: Choice is Power
Choosing to take control of your reproductive health is powerful—but it’s also deeply personal. Whether you’re on birth control to manage periods, avoid pregnancy, or simply own your choices, your autonomy matters.
Even with the best intentions, things can go sideways. And that’s okay. It doesn’t mean you’ve lost control, it means you still have choices. Maybe that’s exploring a different contraceptive method, seeking emergency contraception, or deciding how to handle an unplanned pregnancy.
You’re allowed to pivot. Your body, your decisions.
Which Birth Control is Best for Preventing Pregnancy Completely?
If you are sure about not wanting to carry a pregnancy, consider these highly effective options:
- Long-Acting Reversible Contraceptives (LARCs): IUDs and implants are the best and most practical options for you, as they lower the chances of human error.
- Combination Methods: Taking hormonal birth control plus using condoms provides extra protection. As a bonus, they also prevent STIs.
- Sterilization (if you're sure): You need to be absolutely firm when making this decision as it is permanent. If you’re 100% sure you don’t want kids in the future, this is your best bet while thinking of family planning.
What to Do if Birth Control Fails
- Take a Pregnancy Test: Wait at least a week to take a pregnancy test when you miss your period to increase the test's accuracy.
- Stay Calm: You have options: continue the pregnancy, consider abortion (MTP), or consider adoption.
- Consider Emergency Contraception: In case you have unprotected sex or are doubting birth control failure, the morning-after pill (like Plan B) can help prevent pregnancy if taken within the first 72 hours.
- Book an Appointment: It is always best to confirm with a specialist. A doctor will guide you through whether to confirm a pregnancy or explore the next steps.
Early Signs of Pregnancy While on Birth Control
If you are still thinking, “Could I be pregnant?” look for these early signs:
- Missed period (though there is also a possibility of irregular cycles due to hormonal birth control )
- Nausea or vomiting
- Sore breasts
- Fatigue
- Increased urination
However, it is essential to note that not all of these mean you’re pregnant. But if you’re experiencing multiple symptoms, it’s worth checking.

Frequently Asked Questions (FAQs)
What are the differences between hormonal and non-hormonal birth control?
Hormonal birth control (like pills and IUDs) functions by releasing hormones to prevent ovulation, while non-hormonal options (like copper IUDs and condoms) create physical barriers.
2. Can birth control affect your menstrual cycle?
Yes, it is common to notice lighter, irregular, or even missed periods, especially in the first few months after taking birth control as they can lead to hormonal imbalance.
3. How long does it take for birth control to start working?
It depends on the method. Pills take about 7 days, while IUDs and implants work almost immediately if inserted during your period.
4. Can you get pregnant immediately after stopping birth control?
Yes! Fertility can return quickly after stopping most birth control methods, though it varies by individual.
5. What are the side effects of different birth control methods?
Not everyone experiences the same side effects. But some common ones are nausea, mood changes, headaches, and spotting. You may also experience cramping or heavier periods at first through long-term methods like IUDs.
6. Does birth control protect against sexually transmitted infections (STIs)?
No. Condoms are the only method to protect yourself from STIs.
7. Can birth control cause weight gain?
Some people experience slight weight changes, but studies show no major long-term weight gain linked to most birth control methods.
8. What should you do if you miss a birth control pill?
Take it as soon as you remember. If it's been more than 24 hours, check your pill’s instructions and consider backup contraception.
9. Is it safe to use multiple birth control methods at the same time?
Yes! You shield yourself and your partner from STIs with condoms and taking hormonal birth control ensures pregnancy protection.
10. How often should you see a doctor for birth control management?
Annual check-ups are always ideal, but if you experience side effects, want to switch methods, or have concerns, you can make an appointment sooner.
