What This Guide Covers

Reproductive health touches more than one type of appointment. It includes contraception choices, sexually transmitted infection (STI) testing, menstrual cycle changes, pregnancy planning, fertility questions, and symptoms that need urgent attention. This guide is a map, not a diagnosis. It is written for anyone with a reproductive system, regardless of gender identity, relationship status, sexual activity, or whether pregnancy is a goal, a concern, or not relevant right now.

Use the sections below to identify which type of care applies to your situation, then bring your questions to a licensed healthcare provider who knows your health history.

Quick Care Map: Where Do I Start?

• I want to prevent or plan a pregnancy — see Contraception Basics below.
• I am sexually active or starting a new relationship — see STI Testing Basics below.
• My period feels irregular, heavy, or has stopped — see Understanding Your Cycle below.
• I am thinking about pregnancy in the future — see Pregnancy Planning below.
• I have questions about fertility or trouble conceiving — see Fertility Questions below.
• I have pain, unusual bleeding, or other concerning symptoms right now — see When to Seek Urgent Care below.

Contraception Basics

People consider several factors when choosing a birth control method, including safety, effectiveness, cost and access, side effects, how much day-to-day involvement the method requires, and whether it is reversible or permanent. The Centers for Disease Control and Prevention (CDC) groups contraceptive methods into a few broad categories.

Reversible Methods

• Intrauterine devices (IUDs) — Small devices placed in the uterus by a clinician. The hormonal (levonorgestrel) IUD can stay in place for several years depending on the device, and the copper IUD can remain in place for up to 10 years.
• Hormonal methods — Includes the implant (a thin rod placed under the skin of the upper arm), the injection (given every three months), combined and progestin-only pills, the patch, and the vaginal ring. These are prescribed by a healthcare provider.
• Barrier methods — Includes external (male) and internal (female) condoms, the diaphragm, cervical cap, sponge, and spermicide. External condoms are the only contraceptive method that also helps reduce the risk of HIV and other STIs when used correctly.
• Fertility awareness-based methods — Tracking the menstrual cycle to identify fertile and infertile days. Effectiveness varies depending on the specific method and how consistently it is used.
• Lactational amenorrhea method (LAM) — A temporary method available to some breastfeeding parents in the first months after birth, under specific conditions.
• Emergency contraception — Used after sex without birth control or after a method failure, such as a broken condom. Options include the copper IUD and emergency contraceptive pills; some pills are available over the counter, and effectiveness is generally better the sooner they are used after unprotected sex.

Permanent Methods

• Tubal surgery — A procedure that closes or cuts the fallopian tubes.
• Vasectomy — A procedure that prevents sperm from being present in ejaculate. It takes time and a follow-up test to confirm effectiveness, so another method is typically needed until a provider confirms the sperm count has dropped to zero.

Most contraceptive methods do not protect against STIs, including HIV. Condoms, used alone or with another method, help reduce STI and HIV risk, and pre-exposure prophylaxis (PrEP) is another option for reducing HIV risk. For a closer look at how to compare methods, see our birth control and contraception guide. A healthcare provider can walk through which methods fit your health history and goals.

STI Testing Basics

STIs often cause no symptoms, so testing is the only reliable way to know your status. General screening guidance from the CDC includes:

• Everyone ages 13 to 64 should be tested for HIV at least once.
• Most sexually active adults should be tested for syphilis, with frequency depending on regional risk factors.
• Pregnant women should be tested for syphilis, HIV, hepatitis B, and hepatitis C early in pregnancy, with some needing repeat testing and testing for chlamydia and gonorrhea.
• All sexually active women under 25 should be tested yearly for gonorrhea and chlamydia; some women 25 and older should be tested yearly as well, depending on risk factors such as new or multiple partners.
• Sexually active gay and bisexual men and other men who have sex with men should be tested at least yearly for syphilis, chlamydia, gonorrhea, and HIV, with more frequent testing recommended for those with multiple or anonymous partners.
• Anyone who shares injection drug equipment should be tested for HIV at least once a year.
• Anyone who has had oral or anal sex should ask their provider about throat and rectal testing options.

Ways to Get Tested

• In a healthcare provider’s office, using blood, urine, or swab samples.
• At-home self-testing for some infections, using an FDA-approved test that gives results within minutes.
• Self-collection kits, where you collect your own sample and mail it to a lab, with results typically available in a few days.

If talking to your regular provider feels uncomfortable, confidential and low-cost or free testing is available through many public health clinics. See our STI and sexual health resource page for more on testing options and prevention.

Understanding Your Cycle

Menstrual cycles vary from person to person, and changes in cycle length, flow, or symptoms can have many different causes, from stress and diet to hormonal conditions. There is no single “normal” that applies to everyone. Our menstrual cycles and ovulation guide covers cycle tracking in more depth. If you notice a significant or lasting change from your own typical pattern, that is worth discussing with a provider rather than researching alone.

Signs Worth Mentioning to a Provider

• Periods that stop for several months without a known cause (such as pregnancy)
• Bleeding that regularly soaks through protection every hour or lasts far longer than your usual cycle
• New or worsening pain during your period that interferes with daily activities
• Bleeding between periods or after sex

Pregnancy Planning

Whether you are planning a pregnancy now, in the future, or are undecided, a preconception or planning visit lets a provider review your health history, medications, vaccination status, and any conditions that could affect a pregnancy. This is also the right setting to discuss timelines, spacing between pregnancies, or switching off a contraceptive method when you are ready. Our pregnancy and preconception guide walks through what a planning visit typically covers.

Fertility Questions

Fertility questions can come up whether or not pregnancy is an active goal — for example, understanding your cycle, a past diagnosis, or family planning timing. A reproductive health provider can help evaluate concerns and explain what further testing, if any, would be appropriate for your specific situation. Our fertility evaluation guide explains what that process can involve. General information cannot substitute for that individualized evaluation.

When to Seek Urgent Care

Some symptoms need prompt medical attention rather than general research. Contact a provider or seek urgent/emergency care for:

• Severe pelvic or abdominal pain
• Heavy bleeding that soaks through protection rapidly
• Fever combined with pelvic pain or unusual discharge
• Sudden, severe symptoms in pregnancy, such as heavy bleeding or intense pain
• Any symptom that feels sudden, severe, or unlike anything you’ve experienced before

This is general guidance, not a full symptom checklist. When in doubt, contact a healthcare provider or seek in-person care.

Preventive Care Checklist

• ☐ Confirm whether you’re due for STI testing based on the guidance above
• ☐ Review your current contraceptive method and whether it still fits your life and goals
• ☐ Track your cycle for a few months if you’ve noticed changes
• ☐ Schedule a preconception visit if pregnancy is a near-term goal
• ☐ Write down questions before your next appointment so nothing gets missed

Limitations of This Guide

This article summarizes general public health guidance. It does not account for your personal medical history, medications, allergies, or existing conditions. Screening recommendations can vary by age, location, symptoms, and individual risk factors, and only a licensed provider can tailor guidance to you.

Who Should Be Extra Cautious

• Anyone who is currently pregnant or could be pregnant
• Anyone with a chronic condition (such as a clotting disorder, migraine with aura, or liver disease) that can affect contraceptive safety
• Anyone with symptoms of infection, such as fever, unusual discharge, or pelvic pain
• Anyone unsure of their STI status who is sexually active

Frequently Asked Questions

Do I need a prescription for all birth control methods?

No. Some options, such as external condoms, internal condoms, spermicide, and certain emergency contraceptive pills, are available over the counter. Others, including IUDs, the implant, the pill, the patch, and the ring, require a prescription or an in-office procedure.

Can I get tested for STIs without seeing my regular doctor?

Yes. Options include public health clinics, at-home self-tests for some infections, and mail-in self-collection kits. Even with a self-test, it’s still worth discussing results and next steps with a healthcare provider.

Is irregular bleeding always a sign of a problem?

Not necessarily — cycles can shift for many reasons. But a lasting change from your own normal pattern, or bleeding between periods or after sex, is worth mentioning to a provider rather than waiting it out.

Do I need to plan for pregnancy even if I’m not sure I want kids yet?

A planning or preconception conversation isn’t only for people who are certain. It can help you understand your options, timeline flexibility, and how your current health or medications might factor in whenever you do decide.
