Pregnancy and STDs: What Every Expecting Parent Should Know

Pregnancy is a time filled with excitement, questions, and important decisions about health. For expecting parents, sexual health is an important part of prenatal care, even when there are no obvious symptoms. Sexually transmitted diseases (STDs), also commonly called sexually transmitted infections (STIs), can sometimes affect pregnancy, childbirth, or a newborn's health. The good news is that many STDs can be diagnosed, managed, and treated, and appropriate prenatal care can significantly reduce potential complications.

If you are pregnant and have an STD, you are not alone, and an infection does not automatically mean that you cannot have a healthy pregnancy. The most important steps are to seek professional medical care, receive recommended testing, follow treatment instructions, and communicate honestly with your healthcare provider and partner.

How Common Are STDs During Pregnancy?

STDs are common among sexually active people, including people who become pregnant. The World Health Organization estimates that more than 1 million curable STIs are acquired every day worldwide among people aged 15–49. Common infections include chlamydia, gonorrhea, syphilis, and trichomoniasis, while viral infections such as herpes simplex virus (HSV), human papillomavirus (HPV), and HIV can also affect sexual health.

Because some infections produce few or no symptoms, a person may not know they have an infection. This is one reason STD testing and prenatal screening are important. Having no symptoms does not necessarily mean there is no infection.

Why Are STDs Important During Pregnancy?

An STD can affect pregnancy in different ways depending on the specific infection, when it was acquired, whether it is treated, and the individual's overall health. Some infections can increase the risk of pregnancy complications, while others may potentially be transmitted to a baby during pregnancy, delivery, or after birth.

For example, untreated syphilis during pregnancy can cause serious complications for the baby. HIV can also be transmitted from a pregnant person to their baby without appropriate treatment and medical management. Certain infections can increase the risk of complications around delivery.

These possibilities are reasons for medical attention—not reasons for panic. Early diagnosis and appropriate treatment can make an important difference.

Which STDs Should Be Considered During Pregnancy?

Healthcare providers may recommend screening based on pregnancy, age, sexual history, symptoms, risk factors, and local clinical guidelines. Common infections considered during prenatal care include:

• Chlamydia: Often produces no symptoms but can cause complications if untreated.
• Gonorrhea: Can be asymptomatic and may require treatment during pregnancy.
• Syphilis: Particularly important during pregnancy because untreated infection can seriously affect a developing baby.
• HIV: Testing and effective treatment can greatly reduce the chance of transmission to the baby.
• Hepatitis B: Screening during pregnancy helps healthcare providers plan appropriate protection for the newborn.
• Herpes (HSV): Genital herpes requires special consideration, particularly near delivery.
• HPV: Common and often manageable, although pregnancy can sometimes change symptoms or treatment considerations.

Not every pregnant person will require every possible test at every stage of pregnancy. Your healthcare provider can determine which screenings are appropriate for you.

STD Testing During Pregnancy

STD testing is an important component of reproductive and sexual health. Some infections can be detected through blood tests, while others may require urine or swab samples. Testing recommendations vary according to the infection and individual circumstances.

The Centers for Disease Control and Prevention (CDC) recommends that pregnant women receive certain STI screenings during pregnancy, including testing for HIV, hepatitis B, hepatitis C, and syphilis, with additional testing for infections such as chlamydia and gonorrhea based on age and risk factors.

If you are pregnant and have a new sexual partner, multiple partners, a partner with an STI, or other risk factors, tell your healthcare provider. Additional testing may be appropriate later in pregnancy.

Can You Have a Healthy Pregnancy If You Have an STD?

In many cases, yes. An STD diagnosis does not automatically mean that a pregnancy will be unhealthy. The outcome depends on the particular infection, when it was diagnosed, whether treatment is available, and how closely medical recommendations are followed.

Some bacterial STDs can be treated with antibiotics that are appropriate during pregnancy. Other infections, such as herpes or HIV, cannot currently be cured but can be medically managed. Your healthcare provider can recommend treatment that takes pregnancy into account.

Never stop prescribed medication or begin an STD treatment on your own simply because you are pregnant. Always ask your obstetrician, midwife, or other qualified healthcare professional about medication safety.

Pregnancy and Herpes: What Should You Know?

Herpes simplex virus deserves particular attention because genital herpes can sometimes be transmitted to a newborn during childbirth. The risk is especially important when a person acquires genital herpes for the first time late in pregnancy.

Tell your prenatal care provider if you have a history of genital herpes, even if you currently have no symptoms. Your healthcare team can discuss your history of outbreaks, symptoms, treatment options, and delivery planning.

According to the CDC, women with recurrent genital herpes can often have vaginal deliveries, while the presence of lesions or symptoms at the beginning of labor may affect decisions about delivery.

Pregnancy is not the time to hide an HSV diagnosis out of embarrassment. Giving your healthcare provider accurate information allows them to make an appropriate plan for you and your baby.

What About Sex During Pregnancy If You Have an STD?

Pregnancy does not automatically mean that couples must stop having sex. However, whether sexual activity is appropriate depends on the pregnancy, the specific infection, symptoms, treatment status, and advice from your healthcare provider.

If one partner has an STD and the other partner does not, discuss transmission prevention with a healthcare professional. Condoms and other barrier methods can reduce the risk of some STIs, although they cannot completely eliminate transmission of infections such as herpes or HPV because uncovered skin can also be involved.

If you or your partner has an active outbreak, sores, unusual discharge, pain, or other symptoms, pause sexual activity and seek appropriate medical advice.

How to Protect Yourself and Your Baby

Get Recommended Prenatal Screening

Attend prenatal appointments and complete the STD testing recommended by your healthcare provider. Screening can identify infections that might otherwise go unnoticed.

Tell Your Healthcare Provider Your Full Sexual Health History

Healthcare professionals need accurate information to provide appropriate care. Don't be embarrassed to mention previous STDs, herpes outbreaks, new partners, or concerns about your partner's sexual health.

Follow Treatment Instructions

If an infection is diagnosed, take medications exactly as prescribed. Some infections require partner treatment as well to reduce the possibility of reinfection.

Use Protection When Appropriate

If you are sexually active during pregnancy, ask your healthcare provider about condoms and other protective strategies that are appropriate for your circumstances.

Communicate With Your Partner

Pregnancy and STD conversations can be emotional. Try to approach them as a shared health responsibility rather than a question of blame. An infection does not necessarily indicate when or from whom it was acquired, because some infections can remain undetected for long periods.

Pregnancy, STDs, and Emotional Health

The emotional impact of an STD diagnosis during pregnancy can sometimes be as difficult as the medical questions. A pregnant person may feel fear, guilt, embarrassment, anger, or worry about their baby. These emotions are understandable, but an STD diagnosis does not make someone a bad partner or a bad parent.

Try to separate the medical condition from your sense of self. You are still the same person with your relationships, dreams, personality, career, family, and future. Professional counseling or a trusted healthcare provider can also help when anxiety becomes overwhelming.

Finding Support From People Who Understand

For people living with herpes or another STD, finding others who understand can make difficult conversations feel less isolating. PositiveSingles is a specialized dating and social community designed for people living with herpes and other STIs.

For someone navigating pregnancy, relationships, disclosure, and sexual health, connecting with people who have faced similar experiences can provide emotional support. Community discussions can cover topics such as relationships, disclosure, stigma, communication, and life after an STD diagnosis.

However, online communities should complement—not replace—professional prenatal and medical care. Questions about pregnancy, medications, delivery, transmission to a baby, or treatment should always be discussed with an obstetrician, midwife, or qualified healthcare professional.

A Story of Pregnancy, Honesty, and Support

Imagine a woman who discovers she has genital herpes after becoming pregnant. At first, she worries that the diagnosis has changed everything. She is afraid to tell her partner and even more afraid of what it might mean for her baby.

Instead of hiding the diagnosis, she talks with her prenatal care provider. She learns that genital herpes can be managed and that her medical team can monitor her symptoms and make a delivery plan. She then has an honest conversation with her partner.

The conversation isn't perfect. There are questions, uncertainty, and emotional moments. But they eventually realize that the diagnosis is something they can face together. Her medical team handles the medical decisions, while she and her partner focus on supporting each other and preparing for their baby's arrival.

The story highlights an important lesson: asking for help is not a sign of weakness. When pregnancy and sexual health become complicated, reliable medical information and supportive communication can make the situation much more manageable.
