Contraception and Unintended Pregnancy:

Choosing the right contraceptive method requires a personalized approach that considers a person’s health history, pregnancy goals, lifestyle, privacy needs, and preferences. The best contraceptive counseling includes reviewing effectiveness, side effects, menstrual changes, non-contraceptive benefits, confidentiality, and applicable state laws—especially when prescribing birth control to minors.

Understanding Contraceptive Counseling and Unintended Pregnancy Prevention

Contraceptive visits should focus on patient-centered care, shared decision-making, and creating a confidential environment where individuals feel comfortable discussing their reproductive goals. Healthcare providers should establish rapport and understand each patient’s priorities before recommending a method.

During a contraceptive consultation, providers should:

Review state-specific laws regarding contraception access, including prescribing birth control to minors.
Assess pregnancy intentions and determine whether the patient wants to become pregnant now, later, or never.
Provide preconception counseling when pregnancy is desired in the future.
Recommend appropriate preventive screenings based on age, risk factors, and health history.
Ensure patients understand their contraceptive options and can make informed decisions.

Key Factors in Choosing a Contraceptive Method

A patient’s informed preference should guide contraceptive selection. Counseling should include how each method works, how it is used, effectiveness, possible side effects, and additional health benefits.

Important considerations include:

How the method is taken or administered.
Frequency of use.
Effectiveness in preventing pregnancy.
Effects on menstrual bleeding patterns.
Possible adverse effects.
Non-contraceptive health benefits.
Privacy concerns.
Effects on future fertility.

For individuals actively trying to conceive, prenatal vitamins containing folic acid should be started before pregnancy.

Combined Estrogen-Progestin Contraceptives

Combined hormonal contraceptives contain both estrogen and progestin. These methods include combined oral contraceptive pills, patches, and vaginal rings.

Beyond preventing pregnancy, combined estrogen-progestin methods may provide several additional benefits, including:

Reduced menstrual cramps.
Decreased pelvic pain associated with endometriosis.
Improvement of heavy menstrual bleeding (menorrhagia).
More predictable menstrual cycles.
Reduced symptoms of premenstrual syndrome (PMS).
Lower risk of ovarian cancer.
Lower risk of endometrial cancer.
Reduced development of new ovarian cysts.
Reduced risk of ectopic pregnancy.
Improvement of acne and hirsutism.
Lower risk of benign breast disease.

Screening Before Starting Estrogen-Containing Methods

Before prescribing estrogen-containing contraception, healthcare providers should screen for conditions that increase the risk of complications.

Important medical history questions include:

History of migraines, especially migraine with aura.
Liver disease.
Blood clots or clotting disorders.
Smoking status.
Cardiovascular disease.
Other risk factors for thromboembolism.

The estrogen dose can influence menstrual patterns. Higher estrogen doses are more likely to maintain regular withdrawal bleeding, while lower estrogen doses may result in lighter periods or no periods.

Progestin-Only Contraceptive Methods

Progestin-only contraception is an option for individuals who cannot or prefer not to use estrogen-containing methods. These include injections, implants, and progestin-only pills.

Depo-Provera Injection (DMPA)

The depot medroxyprogesterone acetate (DMPA) injection is a progestin-only contraceptive given every three months.

Benefits include:

Reduced menstrual cramping.
Reduced menstrual bleeding.
Reduced risk of endometrial cancer.

Potential concerns include:

Possible weight gain.
Decreased bone mineral density with long-term use.
Increased risk of osteopenia or osteoporosis if used beyond two years without careful assessment.

Patients using DMPA should receive counseling about adequate calcium intake and bone health.

Nexplanon Implant

The etonogestrel implant (Nexplanon) is a highly effective, long-acting reversible contraceptive placed under the skin of the upper arm.

Key points:

It is one of the most effective reversible contraceptive methods available.
Approximately 10% of users may experience continuous spotting or irregular bleeding.
Fertility generally returns quickly after removal.

Progestin-Only Pills

Progestin-only pills provide contraception without estrogen.

Benefits include:

Reduced risk of endometrial cancer.
Suitable for individuals who cannot use estrogen.

Important counseling points:

The pill must be taken at the same time every day.
Missing or delaying doses can reduce effectiveness.
Incorrect timing may lead to breakthrough bleeding.

Non-Hormonal Copper IUD

The copper intrauterine device (IUD) provides hormone-free contraception and can remain effective for many years.

Possible effects include:

Heavier menstrual bleeding.
Longer menstrual periods.
Increased cramping, especially during the first months after placement.

Hormonal IUD

Hormonal IUDs release levonorgestrel and provide highly effective long-term contraception.

Common effects include:

Spotting during the first months.
Lighter periods over time.
Possible absence of menstruation (amenorrhea).

Many users choose hormonal IUDs because of their effectiveness and ability to reduce menstrual bleeding.

Special Populations and Contraceptive Considerations

Certain populations require additional counseling and individualized contraceptive planning.

Adolescents

Adolescents should receive confidential, developmentally appropriate counseling. Providers should understand state laws regarding contraceptive access and consent.

Postpartum Patients

Most postpartum individuals can begin contraception based on their medical situation and breastfeeding status. A six-week postpartum visit is an important opportunity for contraceptive planning, although some methods may be started earlier.

Postabortion Care

Contraception can often be initiated immediately after abortion if pregnancy prevention is desired.

Patients With Chronic Conditions

Individuals with chronic health conditions should receive contraceptive recommendations based on current medical guidelines, including the CDC Medical Eligibility Criteria for Contraceptive Use.

Special considerations may apply for individuals with:

Obesity.
Substance use disorders.
History of cancer.
Intellectual or developmental disabilities.

Additional Preventive Counseling During Contraceptive Visits

Contraceptive appointments are also opportunities to discuss:

Sexually transmitted infection (STI) screening.
Safer sex practices.
Pregnancy planning.
Preventive healthcare needs.
Individual reproductive goals.

Contraception does not protect against STIs, so barrier methods such as condoms may be recommended for STI prevention.

Selecting Birth Control Based on Patient Goals

A contraceptive choice should match the patient’s specific needs and preferences.

For example, a patient who:

Wants acne improvement.
Prefers lighter periods or no periods.
Wants to avoid weight gain.

May benefit from a combined oral contraceptive such as Yaz (drospirenone/ethinyl estradiol), which contains a progestin that may improve acne symptoms and a low-dose estrogen component that can help reduce menstrual bleeding.
