Birth control decisions come down to three questions: how well does this method actually work, what side effects are you willing to live with, and does it fit your health history. Every method covered here is FDA-approved and used safely by millions of people every year. None of them is the right choice in general. The right choice is the one that matches what you want your next few months or years to look like.
Start with what you want, not a chart
Before effectiveness percentages, answer a few questions for yourself. Do you want your period lighter, gone, or unchanged? Do you want something you set and forget for years, or something you control day to day? Are you done having children, not sure yet, or actively avoiding a procedure that's hard to reverse? Your answers narrow the list fast, and a clinician can help you match your answers to a method once you know what you're looking for.
The most effective reversible methods: IUDs and the implant
The contraceptive implant (a matchstick-sized rod placed under the skin of your upper arm) and intrauterine devices (IUDs) are the most effective reversible birth control available, over 99% effective with typical use because there's nothing to remember day to day. The implant is FDA-labeled for up to 3 years and often stops or lightens periods, though irregular spotting in the first several months is the most common reason people stop using it.
Hormonal IUDs (levonorgestrel) last 3 to 8 years depending on the brand and typically make periods much lighter or absent within a year. Copper IUDs contain no hormones and last up to 10 to 12 years, but they can make periods heavier and crampier, especially in the first few months. Both are inserted in a brief in-office procedure that causes cramping; over-the-counter pain medication beforehand, a support person, and asking your clinician about a numbing option can all help.
Uterine fibroids, which are more common and often more severe in Black women, don't rule out an IUD. A systematic review of women with fibroids using the hormonal IUD found no increase in menstrual bleeding, and blood counts improved in women who kept using it, because the device's local hormone thins the uterine lining. The same review found the device came out (expelled) more often in women with fibroids, particularly larger ones, so a follow-up visit a few months after insertion to confirm it's still in place is worth keeping.
The shot, the pill, the patch, and the ring
The birth control shot (DMPA, brand name Depo-Provera) is about 96% effective with typical use, given as an injection every 3 months. It contains no estrogen, which makes it an option for many people who can't take estrogen-containing methods. The tradeoff is bone density: DMPA use is linked to a measurable drop in bone mineral density that recovers after you stop, and the American College of Obstetricians and Gynecologists advises against stopping the shot solely over bone concerns, since the density loss is reversible and unintended pregnancy carries its own well-documented harms. Other common side effects are irregular bleeding, weight change, and headaches.
The pill, the patch, and the vaginal ring are each about 93% effective with typical use, a gap from their under-1%-failure perfect-use rate that comes almost entirely from missed pills, late patch changes, and forgotten ring swaps. Most versions combine estrogen and a progestin, which is what makes them effective at suppressing ovulation and also what puts them off-limits for some health histories, covered next. Progestin-only pills exist for people who need to avoid estrogen and are about as effective as the combined pill when taken at the same time every day.
Barrier methods and emergency contraception
External (male) condoms are about 87% effective with typical use and internal (female) condoms about 79%; both are the only methods that also reduce the risk of sexually transmitted infections, so many people pair one with a more effective method rather than relying on it alone. Diaphragms, the sponge, and spermicide range from roughly 73% to 86% effective with typical use and need to be used correctly every time to work.
Emergency contraception is backup, not a routine method. A levonorgestrel pill (sold over the counter with no age or ID requirement) works best taken within 72 hours of unprotected sex, though it has some effect up to 5 days, and its effectiveness declines with delay and with higher body weight. A copper IUD placed within 5 days is the most effective emergency option available, and then keeps working as ongoing birth control if you leave it in place.
Permanent methods
Tubal sterilization (commonly called "getting your tubes tied," though most procedures today remove the tubes entirely) and vasectomy for a partner are both over 99% effective and meant to be permanent. Reversal surgery exists but isn't reliable, so this route makes the most sense once you're confident you don't want to carry a future pregnancy, not as a stopgap.
The history behind the hesitation, and why the choice is yours
Distrust of contraceptive counseling in Black communities has a documented history, not a vague one. Eugenics-era sterilization laws beginning in the early 1900s disproportionately targeted Black, Indigenous, and immigrant women, and Medicaid-funded sterilizations continued the pattern into the 1960s and 1970s, most visibly in the 1973 case of two Black sisters, ages 12 and 14, sterilized in Alabama after their illiterate mother signed a consent form she couldn't read, a case (Relf v. Weinberger) that forced new federal informed-consent rules. That history is real, and it's the reason some clinics push harder on consent than others feel is warranted. It's also not a reason to assume what any one person wants. Some readers are looking for the most effective method available. Some want nothing hormonal. Some aren't looking for contraception at all. All three are the right answer if it's yours: the goal of this guide is information, not a recommendation.
Cost and access
If you have private insurance, the Affordable Care Act requires it to cover at least one product in every FDA-approved contraceptive category, including the visit to get it, with no copay or deductible. If you're uninsured or on a tight budget, Title X-funded family planning clinics and federally qualified health centers offer contraceptive care free or on a sliding scale based on income, regardless of immigration status at most sites. Search our directory of community health centers to find one near you. Telehealth contraceptive care, where a clinician prescribes the pill, patch, ring, or shot after an online visit, is also widely available if getting to an appointment is the barrier; ask your existing provider or a clinic on our directory whether they offer it.
Frequently asked questions
Which birth control method is most effective? ▼
The implant and IUDs (hormonal or copper) are the most effective reversible methods, over 99% effective with typical use, because they don't depend on remembering anything day to day. Permanent methods (tubal sterilization and vasectomy) are also over 99% effective.
Can I use birth control if I have high blood pressure? ▼
It depends on how high. With blood pressure in the 140/90 to 159/99 range, estrogen-containing methods like the pill, patch, or ring carry an increased-risk caution; at 160/100 or higher, they're not recommended. Progestin-only pills, the shot, the implant, and both types of IUD don't carry this restriction, so ask your clinician to check your blood pressure and go through the options that fit.
Is the birth control shot safe if I have sickle cell disease? ▼
Current federal guidance places the shot in a caution category for sickle cell disease because of clotting risk, and advises against combined hormonal methods (pill, patch, ring) entirely. The hormonal IUD, the implant, and progestin-only pills are rated safest. Talk with a clinician familiar with your sickle cell history before starting or continuing any hormonal method.
Will an IUD make my fibroids worse? ▼
No. Research on the hormonal IUD in women with fibroids found it doesn't increase bleeding and often reduces it, because the hormone works locally on the uterine lining. The device does come out more often in women with larger fibroids, so a follow-up check a few months after insertion is worth scheduling.
How much does birth control cost with and without insurance? ▼
With most private insurance, contraception is covered with no copay under the ACA. Without insurance, Title X clinics and federally qualified health centers offer free or sliding-scale contraceptive care based on income; find one through our clinic directory.
