Quick Answer: Chlamydia during pregnancy can cause serious complications like premature birth, miscarriage, and newborn infections, even without symptoms. Get tested early, retest in the third trimester if needed, and treat it immediately with pregnancy-safe antibiotics.
Who This Guide Is For (And Why It Matters)
Maybe you’re newly pregnant and wondering what prenatal testing actually covers. Maybe you’ve had a new partner and feel a quiet worry you can’t shake. Or maybe you’re someone who’s been told they “don’t look like” they’d have an STD. This guide is for you, for the people who fall through the gaps of routine screening, or who just didn’t know that chlamydia can fly under the radar.
Let’s be real: asking for an STD test while pregnant can feel like a confession. But it shouldn’t. Testing is care, not shame. It’s about protecting both your health and your baby’s, no matter what your past looks like. That’s why this article pulls no punches. We’re going to talk about what testing looks like at home and in clinics, how chlamydia can affect a pregnancy, and why even “normal-looking” discharge can hide a deeper issue.
What Happens When Chlamydia Is Missed in Pregnancy?
When left untreated, chlamydia isn’t just an infection, it’s a silent saboteur. It can travel up from the cervix into the uterus, triggering inflammation that weakens the membranes around your baby. This increases the risk of your water breaking early, also known as preterm premature rupture of membranes (PPROM). In some cases, it contributes to low birth weight or early labor before 37 weeks.
But that’s not all. During delivery, the infection can pass directly to the baby. Newborns exposed to chlamydia in the birth canal can develop eye infections (conjunctivitis) or pneumonia within the first few weeks of life. According to the CDC, about 60% of exposed infants develop conjunctivitis, and up to 20% develop pneumonia.
None of this is meant to shame, it’s meant to spotlight the quiet but preventable risks. Many people who experience pregnancy loss or complications are never told their infection status could have played a role. You deserve to know, and you deserve better than silence.

What Prenatal Tests Might Miss
Here’s a hard truth: even if you’re getting regular prenatal care, you might not be screened for chlamydia unless you’re under 25, have new or multiple partners, or live in a state that mandates testing. That means a lot of people are slipping through the cracks, especially those in long-term relationships who don’t consider themselves “high risk.”
Jess, 33, found this out the hard way. “I had one partner during pregnancy, and we were monogamous, or so I thought. I assumed my first prenatal blood panel covered everything. It didn’t.” By the time she got tested (in her third trimester, due to discharge and back pain), her infection had been present for months. Her baby was born two weeks early and treated for conjunctivitis within days.
Stories like Jess’s are common. The reality is: no test happens unless you ask or unless your provider flags you. That’s why it’s crucial to know your options, and to act on them without waiting for permission.
How Chlamydia Symptoms Look Different in Pregnancy
If you’re pregnant, your body is already going through massive hormonal changes, and that includes your vaginal environment. Increased discharge? Totally normal. Mild cramping? Happens. So how do you know if what you’re feeling is just pregnancy, or something more?
That’s the trick: most people with chlamydia have no symptoms at all. But when symptoms do show, they can include increased discharge with a yellowish tint, burning when you pee, lower abdominal pain, or pain during sex. In pregnancy, many of these signs overlap with common experiences, which makes detection even harder without a test.
If you’re noticing anything unusual, especially if you’ve had a new partner, haven’t been tested recently, or are unsure of your partner’s status, don’t brush it off. Get tested. Even if it’s “probably nothing.” That’s how protection starts: by staying curious, not complacent.

What Testing Looks Like (And Why It’s Worth It)
You don’t need to wait for your OB-GYN to test you. In fact, many pregnant people use STD Rapid Test Kits for fast, discreet results, especially if they’re between appointments, traveling, or just want peace of mind. At-home chlamydia tests use a simple urine or swab sample and can be mailed or read on-site depending on the kit type.
Your provider may use a nucleic acid amplification test (NAAT) to test for chlamydia in a clinic. This is the best way to find chlamydia. It's highly sensitive and safe during pregnancy. But again, it has to be requested in most cases unless your age or sexual history prompts it automatically.
If cost or privacy is a concern, don’t assume you have to choose between nothing and everything. You can order a discreet chlamydia test kit without stepping into a clinic, and get results fast. Your health, and your baby’s, is worth that clarity.
Untreated vs. Treated: What the Data Tells Us
Let’s look at how chlamydia affects pregnancy outcomes when treated early versus when it goes undetected. This is where the science gets clear, and your decisions can make a life-altering difference.
| Outcome | With Untreated Chlamydia | With Timely Treatment |
|---|---|---|
| Preterm Birth | 2x higher risk | Comparable to uninfected pregnancies |
| Neonatal Conjunctivitis | Up to 60% of exposed infants | Rare when treated before delivery |
| Newborn Pneumonia | 10–20% risk | Highly reduced |
| Miscarriage (early infection) | Increased inflammation, potential contributor | Lowered when detected early |
Table 1: Comparing outcomes in pregnancies with untreated versus treated chlamydia. Data reflects CDC and peer-reviewed studies.
Case Scene: “I Had No Symptoms. My Partner Did.”
Leila, 29, was 22 weeks pregnant when her partner tested positive for chlamydia during routine STI screening. “He swore it must’ve been old. That it didn’t mean anything,” she said. “But I had no signs. No discharge. No pain. I almost didn’t get tested.”
When she did, the result came back positive. Her provider prescribed a pregnancy-safe antibiotic (usually azithromycin or amoxicillin), and she was retested again in her third trimester. “I couldn’t believe how easy the treatment was. But the thought of what might’ve happened if I’d waited, scares me even now.”
Leila’s story isn’t rare. Many pregnant people discover their own STI status only after a partner’s result, or after something goes wrong. Don’t wait for that wake-up call. You don’t need symptoms to justify a test.
When to Test, and When to Retest
The CDC recommends that all pregnant people under 25, and those with risk factors, be screened for chlamydia at their first prenatal visit. But if you’re over 25, or if your provider didn’t bring it up, here’s a general guide:
| Stage of Pregnancy | Recommended Testing | Why It Matters |
|---|---|---|
| First Trimester | Initial screening | Establish early risk and treat before complications |
| Second Trimester | Retest if new exposure or symptoms | Midpoint window for repeat risk |
| Third Trimester | Retest for high-risk individuals or treated infections | Ensure the infection is cleared before delivery |

If you were treated earlier in pregnancy, it’s smart to get rechecked, even if your partner was treated too. Reinfection is common, especially if one partner wasn’t fully treated or if testing happened outside the recommended window period.
How to Talk to Your Partner (Even If It’s Complicated)
Testing positive for chlamydia during pregnancy can stir up everything, fear, guilt, blame. But here's the truth: this is a bacterial infection, not a betrayal diagnosis. Yes, it can come from a new partner. It can also come from a previous relationship, lie dormant, and show up later. Either way, the priority now is care, not conflict.
Sami, 31, found out she had chlamydia at 10 weeks pregnant. “I was more afraid to tell my boyfriend than I was of the infection,” she said. “But the nurse reminded me, he needs treatment too, or we’ll keep passing it back and forth.”
She chose a text script her provider offered: “Hey, I tested positive for chlamydia during pregnancy testing. It’s treatable and common, but you’ll need to get checked too.” No blame. Just facts. He got treated. They both retested. Baby was born healthy.
Disclosing your result can feel terrifying, but silence only increases the risk of reinfection. If you’re scared for your safety, talk to a provider or support line about how to share or whether you should. You don’t owe access to anyone who makes you feel unsafe. But you do deserve support.
Testing Positive: What Happens Next?
The good news? Chlamydia is curable, even during pregnancy. Treatment typically involves a single dose of azithromycin or a short course of amoxicillin, both considered safe for pregnant bodies. If your test was mail-in, you’ll receive results and follow-up instructions. If you tested in a clinic, you’ll likely be offered medication on the spot.
After treatment, it’s vital to avoid sexual contact for seven days and ensure your partner is treated too. Most guidelines recommend retesting after three weeks to confirm clearance and again in the third trimester if there’s any chance of reinfection.
There’s no shame in treatment. It’s not a mark of failure, it’s a sign that you took action. And in pregnancy, that action can literally save a life.
Emotional Fallout Is Real, But You’re Not Alone
Too many people carry guilt after a positive STD test, especially during pregnancy. But you didn’t cause this. You’re navigating a system that often fails to educate, screen, or normalize care. And if your partner wasn’t honest or didn’t know their status, that’s not on you.
Tasha, 27, said she felt “dirty” when her test came back positive. “Like I failed my baby somehow,” she recalled. Her midwife reminded her: “You protected your baby by getting tested. That’s what matters now.”
You’re not dirty. You’re proactive. You’re informed. And you’re taking care of both of you. That’s what real strength looks like.
Retesting: When, Why, and How
Even after treatment, retesting matters. Here's how to think about it:
✔️ After treatment? Wait at least three weeks to confirm the infection is gone. This avoids false positives from leftover DNA.
✔️ Still pregnant after treatment? Retest in the third trimester to ensure your baby isn’t at risk during delivery.
✔️ Unsure if your partner was treated? Retest yourself after any exposure. Don’t rely on promises, rely on your own peace of mind.
If you’re ready to test again, STD Rapid Test Kits has discreet options shipped to your door. Testing is power. Retesting is protection.
Your Privacy Matters
One of the biggest fears around testing for STDs during pregnancy isn’t the test, it’s who might find out. With home testing, you stay in control. STD Rapid Test Kits ships in plain, unbranded packaging. There are no embarrassing labels, no clinic lines, and no one reading your results but you.
Shipping usually takes 2–4 business days. Results depend on the kit type, some offer instant readouts at home, others involve mailing to a lab. Either way, you keep ownership of your timeline. And that’s something every parent-to-be deserves.

What No One Told Me at My First Prenatal Visit
Here’s something I wish someone had said when I walked into my first prenatal appointment: “You should get tested for chlamydia, even if you feel fine. Even if you trust your partner. Even if you’ve only had one.” But no one said that. I was offered a blood draw, a urine cup, and a folder full of appointment cards. No one mentioned STDs.
That’s not unusual. In fact, it’s painfully common. Unless you fit a very specific box, under 25, multiple recent partners, certain zip codes, you might never be offered chlamydia testing during pregnancy. And if you don’t ask, it often won’t happen.
But here’s what that oversight can cost: an infection that climbs silently. A baby born early. An eye infection that needs drops at two days old. A respiratory issue that no one traces back to your cervix. All because the system assumed you didn’t “need” the test.
When you start to question whether you should ask for screening, remember: you're not asking because you did something wrong. You’re asking because you deserve to know what’s going on in your body, and what risks you can remove for your baby. That’s not fear. That’s love.

FAQs
1. Can I really have chlamydia during pregnancy and not feel a thing?
Yes, and that’s exactly what makes it so sneaky. Most people don’t get the burning or discharge you’d expect. You could be 8 months in, nesting hard, feeling fine… and still be carrying a silent infection. That’s why testing is about protection, not paranoia.
2. How would chlamydia even affect my baby?
It’s not just about you anymore. If untreated, chlamydia can cause early labor, low birth weight, and infections in your newborn’s eyes or lungs. Picture a tiny infant needing antibiotics at two weeks old, it’s heartbreaking, and preventable. The fix? A quick test, a simple treatment, and peace of mind.
3. Wait, is it even safe to treat STDs during pregnancy?
Absolutely. Your provider won’t hand you anything risky. Treatments like azithromycin or amoxicillin are commonly used during pregnancy and safe for your baby. Think of it as wiping out the risk before it ever reaches them.
4. What if I already gave birth and just found out I had chlamydia?
Take a deep breath. First step: talk to your baby’s doctor. They might want to check for eye infections or respiratory symptoms. Many newborn exposures are treatable, but early care is key.
5. Do I really have to tell my partner?
If there’s any chance you’re still sleeping together, or might be again, then yes, it’s not just fair; it’s necessary. They need treatment too, or you’ll end up passing it back and forth like a bad ping-pong match. If the convo feels impossible, some clinics can help with scripts or even anonymous notifications.
6. What if my partner won’t get tested or swears they’re fine?
Then you look out for you. Get retested yourself, use protection, and know that denial doesn’t equal safety. You’re not being “dramatic”, you’re being responsible. And if they won’t step up, you’re still allowed to protect your peace.
7. How long should I wait before retesting?
Give it at least three weeks after treatment to retest. Any sooner and you might catch leftover DNA, not live infection. Also: if you’re still pregnant, retest again later in your third trimester to be sure the coast is clear before birth.
8. Will this show up in my medical record?
Only if you go through a clinic. At-home testing? That’s private. No insurance codes. No awkward office chats. Just your result, your timeline, your decision.
9. What if I got it from a past partner and I’m just finding out now?
You’re not alone. Chlamydia can linger silently for months. Maybe even years. That doesn’t make you “gross.” It makes you human, and one smart enough to finally check in and break the cycle.
10. Is home testing accurate enough to trust while pregnant?
Yes, especially if you're using a NAAT-based lab test (many mail-in kits are). Rapid tests can be useful too, especially if you’re in a pinch. Just follow instructions closely and retest through a lab if anything feels off.
