Birth Control Options Explained: Pills, IUDs, Implants & More

If you’ve ever tried to compare birth control options and ended up more confused than when you started, you’re in good company. With more choices available today than at any point in history, finding the right method genuinely takes some thought and ideally, a conversation with a provider who knows your health history.

At Centre OB/GYN, contraception counseling is a core part of our gynecology services. We’re not here to tell you what to choose: we’re here to make sure you have the information you need to choose well. Here’s a comprehensive overview of the options available.

How to Think About Birth Control

Every method involves trade-offs. The “best” birth control is the one that fits your body, your life, and your goals — not just the one with the highest efficacy rate on paper. As you consider your options, it helps to think through:

• How important is it that you never have to think about contraception?
• Do you want to preserve fertility for when you’re ready?
• Are you also looking for help with period management, acne, or PMS?
• Do you want a hormone-free option?
• How do you feel about an insertion procedure vs. a daily habit?

Your answers matter. Let’s walk through what’s available.

Short-Acting Hormonal Methods

These methods require daily, weekly, or monthly use and use synthetic hormones: estrogen, progestin, or both to prevent pregnancy primarily by suppressing ovulation.

The Combination Pill

The most commonly prescribed hormonal method, the combination pill uses both estrogen and progestin. When taken correctly every day, it’s about 91–99% effective. Beyond pregnancy prevention, the pill can significantly improve painful or heavy periods, regulate cycles, reduce PMS, and clear hormonal acne; which is why many women use it for reasons beyond contraception.

The biggest challenge: consistency. A missed pill, particularly early in a pack, can reduce effectiveness. For some women, estrogen-containing methods aren’t appropriate, due to migraines with aura, history of blood clots, high blood pressure, or certain other conditions.

The Progestin-Only Pill (Mini-Pill)

For women who can’t take estrogen, including breastfeeding moms, the mini-pill is a progestin-only alternative. It must be taken at the same time every day (within a 3-hour window) to be effective, which makes it less forgiving than the combination pill.

The Patch and the Ring

The patch (worn on the skin and changed weekly) and the vaginal ring (inserted monthly and changed every 3–5 weeks, depending on the brand) both use estrogen and progestin but offer a more hands-off experience than daily pills. Both are roughly as effective as the combination pill when used correctly.

The Shot (Depo-Provera)

A progestin injection is given in our office every three months. Highly convenient for those who prefer not to manage contraception daily or monthly. One important note: fertility can take longer to return after stopping the shot, sometimes up to 12–18 months, so it may not be the right choice if you’re planning a pregnancy in the near future.

Long-Acting Reversible Contraceptives (LARCs)

LARCs are consistently among the most effective forms of birth control available, with failure rates under 1% — not because they require more discipline, but because there’s nothing to remember. They’re also fully reversible, and fertility typically returns promptly after removal.

IUDs (Intrauterine Devices)

An IUD is a small, T-shaped device placed in the uterus by a provider during an in-office visit. There are two types:

• Hormonal IUDs (Mirena, Kyleena, Liletta, Skyla): Release a small amount of progestin locally. Depending on the brand, they’re effective for 3–8 years. Most women experience significantly lighter periods over time; some stop having periods altogether. Because the progestin acts locally rather than systemically, hormone-related side effects tend to be minimal.
• Copper IUD (Paragard): The only non-hormonal LARC. Effective for up to 10–12 years and works immediately upon insertion. May cause heavier or crampier periods, especially in the first few months. Also the most effective form of emergency contraception when inserted within 5 days of unprotected sex.

IUD insertion is performed in our office. The procedure takes only a few minutes, though some women experience cramping during and shortly after. We take time to talk through what to expect and make the experience as comfortable as possible.

Nexplanon (The Implant)

Nexplanon is a small, flexible rod — about the size of a matchstick — inserted just under the skin of the inner upper arm. It releases a continuous low dose of progestin and provides over 99% effectiveness for up to three years. It’s one of the most effective methods available and is completely hands-off once placed.

The implant is a great option for women who want highly effective, long-term contraception without a daily or monthly routine. Insertion and removal are quick in-office procedures. Some women experience irregular spotting, especially in the first few months, while others have lighter periods or none at all.

Barrier Methods

Barrier methods physically prevent sperm from reaching an egg. They don’t affect hormones, which makes them appealing for women who prefer to avoid systemic effects;though they require consistent and correct use for effectiveness.

• Male condom: The only method that also significantly reduces STI transmission risk. About 85–98% effective depending on use.
• Female condom (internal condom): Inserted before sex; offers STI protection as well as contraception.
• Diaphragm and cervical cap: Used with spermicide, inserted before sex. Less commonly used today due to the need for fitting, spermicide, and precise placement. Offer no STI protection.

Emergency Contraception

Emergency contraception (EC) is used after unprotected sex or method failure; it’s not intended as a routine contraceptive.

• Plan B (levonorgestrel): Available over the counter. Most effective within 72 hours of unprotected sex, though it can work up to 120 hours. Less effective at higher body weights.
• Ella (ulipristal acetate): Prescription only. Effective for up to 5 days and maintains effectiveness regardless of weight.
• Copper IUD: The most effective EC available: over 99% effective when inserted within 5 days. Also provides ongoing contraception for up to 10 years. Our team can discuss IUD insertion if this is something you’re considering.

Permanent Contraception

For women who are certain they don’t want future pregnancies, permanent options offer the most definitive solution.

• Tubal ligation (tube tying): A surgical procedure that closes or removes the fallopian tubes, preventing eggs from reaching the uterus. Highly effective and considered permanent, though reversal is possible (with variable success rates).
• Bilateral salpingectomy: Removal of both fallopian tubes. Increasingly recommended over traditional ligation because it also reduces ovarian cancer risk.

These procedures can often be performed using minimally invasive or robot-assisted techniques, which reduce recovery time significantly. Our board-certified providers can walk you through what’s involved and help you determine whether permanent contraception is the right fit for your goals.

Finding the Right Fit

If you’re switching methods, starting for the first time, or reconsidering something that hasn’t been working well for you, a contraceptive counseling visit is a great place to start. We’ll review your health history, discuss your priorities, and help you think through the options that make the most sense for where you are right now.

And if the first choice doesn’t turn out to be the right one, that’s okay too; most methods are easy to change.
