Finding out you’re pregnant can bring a wave of emotions. You might be thinking about your health, your future, and what this means for your next steps. It can feel like a lot to process all at once.


If you’re navigating questions about pregnancy and STIs, you’re not alone. Many women face similar concerns, and it’s okay to take things one step at a time. With clear information and the right support, you can move forward with confidence.


Understanding the risks and knowing when to seek care can help you protect both your health and your baby’s well-being.

Pregnancy and STIs: What You Need to Know

When it comes to pregnancy and STIs, having clear and accurate information matters. Sexually transmitted infections are more common than many people realize, and they can affect anyone who is sexually active.


Some STIs may not cause noticeable symptoms, which means it is possible to have an infection without knowing it. During pregnancy, untreated STIs can impact your health and may also affect your baby’s development.


The good news is that many STIs can be treated, and early detection can help reduce risks. Knowing your status gives you the opportunity to take steps that support a healthier pregnancy.


If you have questions or concerns, it is okay to ask. Getting the facts is an important part of taking care of yourself.


How Common Are STIs During Pregnancy

Many women are surprised to learn how often STIs occur during pregnancy. These infections affect a significant number of pregnant women each year, even among those who may not think they are at risk.


One of the challenges is that STIs do not always come with obvious signs. You can feel healthy and still have an infection, which is why testing plays such an important role in prenatal care.


Certain age groups, especially younger women, tend to see higher rates of infection. This makes it even more important to stay informed and proactive about your health.


If you have never been tested or are unsure of your status, you are not alone. Taking that first step can help you better understand your health and what care you may need moving forward.


How Untreated STIs Affect Pregnancy

Untreated STIs can lead to complications during pregnancy, especially if they are not detected early. Some infections may increase the risk of issues like inflammation, infection, or preterm labor.


In certain cases, untreated STIs can also raise the risk of miscarriage or other pregnancy concerns. Because symptoms are not always obvious, these risks can develop without warning.


The good news is that many STIs can be treated once identified. Early testing gives you the chance to protect your health and reduce potential complications.


Risks to Your Baby From Untreated STIs

Untreated STIs during pregnancy can affect your baby’s health, sometimes in serious ways. Some infections can be passed to your baby during pregnancy or delivery.


Depending on the type of STI, this can lead to complications such as low birth weight, premature birth, or infections after birth. In certain cases, it may also impact a baby’s development or lead to ongoing health concerns.


Because these effects are not always immediately visible, it’s important to understand how untreated infections can impact both you and your baby.


Common STIs That Can Impact Pregnancy

Several sexually transmitted infections can affect pregnancy. Understanding the most common ones can help you feel more informed and aware of potential risks.


  • Chlamydia

Often has no symptoms, but can lead to complications such as preterm labor or infection in the baby during delivery.


  • Gonorrhea

May increase the risk of miscarriage, premature birth, or eye infections in newborns if left untreated.


  • Syphilis

A serious infection that can be passed to the baby during pregnancy and may lead to severe health complications if not addressed.


  • Herpes (HSV)

Can be transmitted to the baby during delivery, especially if an active outbreak is present at that time.


  • Human Papillomavirus (HPV)

Usually does not directly affect pregnancy, but certain strains may cause complications in rare cases.



  • HIV

Can be passed to the baby during pregnancy, labor, or breastfeeding without proper medical management.


Each of these infections can look different and may not always cause noticeable symptoms. Knowing what to watch for can help you better understand your health during pregnancy.

STI Symptoms to Watch For During Pregnancy

Some STIs can cause noticeable symptoms, while others may go unnoticed. Paying attention to changes in your body can help you recognize when something may not be right.


Common symptoms to watch for include:


  • Unusual vaginal discharge
  • Burning or pain during urination
  • Lower abdominal or pelvic pain
  • Pain during sex
  • Sores, bumps, or rashes in the genital area
  • Itching or irritation


It is important to remember that many STIs do not show clear symptoms at all. You can feel completely fine and still have an infection.


If something feels off or different, it is okay to ask questions and seek clarity. You deserve to understand what is happening in your body.


When to Get Tested for STIs in Pregnancy

Testing for STIs is a normal part of taking care of your health during pregnancy. Many women are tested early on, even if they do not have symptoms.


You may consider getting tested:


  • At the beginning of your pregnancy
  • If you have a new partner or multiple partners
  • If you notice any unusual symptoms
  • If a partner has been diagnosed with an STI
  • If you have not been tested recently


Because some infections do not show symptoms, testing is often the only way to know for sure.
