Pregnancy Discharge: What's Normal and What's Not

TL;DR

• Increased vaginal discharge during pregnancy is completely normal — it's called leukorrhea.
• Normal pregnancy discharge is thin, white or clear, mild-smelling or odorless.
• Changes in color (green, yellow, gray), strong odor, or itching/burning could indicate an infection.
• Always tell your provider about discharge changes — infections during pregnancy are treatable and important to catch early.

Nobody Talks About This, But Everyone Experiences It

Here's something most pregnancy books gloss over: you're going to have a lot more vaginal discharge than usual. Like, noticeably more. Some people go through multiple pantyliners a day.

It's one of those symptoms that feels embarrassing to bring up, even to your provider. But it's one of the most universal pregnancy experiences, and understanding what's normal can save you a lot of unnecessary worry.

What Normal Pregnancy Discharge Looks Like

Normal pregnancy discharge — called leukorrhea — is:

• Thin and milky in consistency
• White or clear in color
• Mild-smelling or odorless
• More abundant than your pre-pregnancy normal

You might notice it starting in early pregnancy and increasing as you progress. This is your body doing exactly what it should — producing more discharge to protect the birth canal from infection and maintain a healthy balance of bacteria.

Why Discharge Increases During Pregnancy

Several things work together to increase discharge:

• Higher estrogen levels stimulate the cervical glands to produce more mucus
• Increased blood flow to the vaginal area
• Your body's protective instinct — extra discharge creates a barrier against bacteria entering the uterus
• The mucus plug forming in your cervix (which you may eventually lose before labor)

What's NOT Normal: Signs to Watch For

While increased discharge is normal, certain changes can indicate an infection or other issue that needs treatment.

Yeast Infection

Yeast infections are more common during pregnancy because hormonal changes alter the vaginal pH.

Signs:

• Thick, white, cottage cheese-like discharge
• Intense itching or burning
• Redness or swelling around the vulva
• Pain during urination or sex

What to do: Call your provider. Don't use over-the-counter treatments without checking first — some aren't safe during pregnancy.

Bacterial Vaginosis (BV)

BV is caused by an imbalance of vaginal bacteria and is important to treat during pregnancy because it's associated with preterm birth.

Signs:

• Thin, grayish-white discharge
• Strong fishy odor, especially after sex
• Burning during urination

What to do: Contact your provider. BV is easily treated with antibiotics that are safe during pregnancy.

Sexually Transmitted Infections

Some STIs cause discharge changes and need treatment to protect both you and your baby.

Signs to watch for:

• Green or yellow discharge
• Foul-smelling discharge
• Discharge accompanied by pelvic pain or fever
• Sores, bumps, or blisters in the genital area

What to do: Contact your provider right away. Most STIs can be safely treated during pregnancy, and early treatment protects your baby.

Amniotic Fluid Leak

In later pregnancy, it's important to distinguish between discharge and leaking amniotic fluid.

Signs of amniotic fluid:

• Thin, clear, and watery (not thick or mucus-like)
• May come in a gush or a steady trickle
• Odorless or slightly sweet-smelling
• Continues to leak when you change position

What to do: If you think you might be leaking amniotic fluid at any point in pregnancy, contact your provider or go to the hospital immediately.

How to Stay Comfortable

• Wear pantyliners — change them frequently to stay dry
• Choose cotton underwear — breathable fabric helps prevent moisture buildup
• Don't douche — ever, but especially not during pregnancy. Douching disrupts your natural bacterial balance
• Wipe front to back — this prevents bacteria from the rectum reaching the vagina
• Skip scented products — scented soaps, sprays, and wipes can irritate and disrupt your natural balance
• Wear loose-fitting clothes — tight pants and synthetic fabrics trap moisture
• Stay dry — change out of wet bathing suits or workout clothes promptly

When to Call Your Provider

Contact your provider if you notice:

• A change in color — green, yellow, gray, or dark brown discharge
• A strong or foul odor — fishy, unpleasant, or noticeably different
• Itching, burning, or soreness in or around your vagina
• Pain during urination
• Blood-tinged discharge (different from spotting — see our article on spotting)
• Watery discharge that feels like it could be amniotic fluid
• Any discharge that just seems "off" compared to your normal

Don't feel embarrassed about bringing this up. Your provider discusses discharge all day long. It's a completely routine topic in prenatal care, and catching infections early is important for your health and your baby's.

The Mucus Plug: What to Expect Later

Toward the end of pregnancy, you may lose your mucus plug — the thick collection of mucus that has been sealing your cervix throughout pregnancy. It can come out all at once (like a glob of thick, jelly-like mucus, sometimes tinged with blood called "bloody show") or gradually over several days.

Losing your mucus plug is a sign that your body is preparing for labor, but it doesn't mean labor is imminent. It can happen days or even weeks before delivery. Mention it to your provider at your next appointment, or call if you're preterm.

The Bottom Line

More discharge during pregnancy is one of those things that's totally normal, somewhat annoying, and rarely discussed. Now you know what to expect, what's normal, and what to watch for.

When in doubt, ask your provider. There's no such thing as a silly question when it comes to your health during pregnancy.
