Increased vaginal discharge at 37 weeks pregnant is typically normal and signals your body preparing for labor, but sudden changes should be checked immediately.
Understanding Vaginal Discharge at 37 Weeks Pregnant
Vaginal discharge during pregnancy is a common and natural occurrence, especially as you approach the final weeks. At 37 weeks pregnant, increased discharge often indicates that your body is gearing up for labor. This discharge, medically known as leukorrhea, consists of cervical mucus combined with vaginal secretions. It serves an important protective role by keeping the birth canal clean and preventing infections.
At this stage, the discharge may become thicker or more abundant due to hormonal changes and cervical softening. Progesterone levels remain high, stimulating glands in the cervix to produce more mucus. This increase can also be influenced by the baby’s position and pressure on the cervix as it begins to descend into the pelvis.
While an uptick in discharge is usually harmless, it’s vital to observe its color, consistency, and odor. Normal discharge tends to be clear or milky white with a mild smell. Any dramatic changes could signal infection or other complications requiring prompt medical attention.
Why Does Discharge Increase at 37 Weeks?
Several physiological factors contribute to increased discharge at this late stage of pregnancy:
- Cervical Ripening: The cervix softens and thins (effacement) in preparation for delivery, releasing mucus plug remnants that increase discharge volume.
- Hormonal Shifts: Elevated estrogen levels enhance blood flow to the vaginal area and stimulate secretions.
- Pressure from Baby: The baby’s head pressing against the cervix can cause minor irritation and promote mucus production.
- Immune Defense: The body produces more mucus to protect against bacteria entering through the birth canal.
This combination of factors means increased discharge is often a sign your body is doing exactly what it should—getting ready for labor.
Characteristics of Normal vs. Abnormal Discharge
Knowing what’s normal helps you spot warning signs early. Here’s how typical discharge compares with problematic types:
| Feature | Normal Discharge | Abnormal Discharge |
|---|---|---|
| Color | Clear, white, or slightly yellowish | Green, gray, bright yellow, or blood-tinged |
| Consistency | Thin to slightly thick; mucous-like | Thick cottage cheese-like or frothy |
| Odor | Mild or no odor | Strong fishy or foul smell |
| Amount | Slight increase expected around 37 weeks | Sudden heavy gush or continuous leaking (possible amniotic fluid) |
| Sensation | No itching or burning; comfortable feeling | Itching, burning, irritation, pain during urination or intercourse |
If you notice any abnormal characteristics in your discharge at this stage of pregnancy, seek medical advice promptly. These symptoms could indicate infections like bacterial vaginosis or yeast infections that may affect labor or baby’s health.
The Mucus Plug and Its Role in Discharge Changes
One key factor behind increased vaginal discharge at 37 weeks pregnant is the mucus plug. This thick collection of cervical mucus seals the cervix during pregnancy to protect against pathogens.
As labor approaches, the cervix dilates and effaces, causing parts of this plug to dislodge naturally. When expelled, it appears as a thick blob of mucus mixed with blood streaks—often called “bloody show.” This event may happen days before labor begins but can also occur right at its onset.
The loss of the mucus plug increases overall vaginal secretions temporarily but is completely normal unless accompanied by heavy bleeding or severe pain.
The Difference Between Amniotic Fluid Leak and Increased Discharge
At 37 weeks pregnant increased discharge can sometimes be confused with amniotic fluid leakage—a sign that membranes around your baby have ruptured (“water breaking”). Differentiating these two is crucial because ruptured membranes require immediate medical evaluation.
Here’s how you can tell them apart:
- Discharge: Usually thick or thin but sticky; no strong odor; no continuous wetness.
- Amniotic Fluid Leak: Watery consistency; continuous trickle or gush; often odorless but sometimes sweet-smelling; wetness persists despite changing positions.
- Tactile Sensation: Amniotic fluid leaks tend to soak underwear quickly and may feel like a constant leak rather than intermittent secretion.
- Timing: Amniotic fluid leakage typically signals labor onset soon after membrane rupture.
If unsure whether you’re experiencing increased discharge or amniotic fluid leakage, contact your healthcare provider immediately for assessment.
The Impact of Infections on Vaginal Discharge at 37 Weeks Pregnant
Infections are a significant concern when noticing changes in vaginal discharge late in pregnancy. Common infections include bacterial vaginosis (BV), yeast infections (candidiasis), and sexually transmitted infections (STIs).
Each condition alters discharge differently:
- Bacterial Vaginosis: Thin grayish-white discharge with strong fishy odor; may cause mild irritation but sometimes no symptoms.
- Candidiasis (Yeast Infection): Thick white “cottage cheese” like discharge accompanied by itching and burning sensations.
- Trichomoniasis (STI): Frothy yellow-green foul-smelling discharge with discomfort during urination.
These infections can complicate delivery if left untreated by increasing risks such as preterm labor or neonatal infection. Therefore, any abnormal symptoms should prompt timely testing and treatment.
Caring for Yourself During Increased Discharge at 37 Weeks Pregnant
Managing increased vaginal discharge effectively involves simple hygiene practices coupled with careful monitoring:
- Avoid Douching:Douching disrupts natural bacterial balance and increases infection risk.
- Select Breathable Clothing:Cotton underwear helps keep the area dry and reduces irritation.
- Mild Cleansing:Cleansing with warm water only; avoid harsh soaps that can alter pH levels.
- Avoid Irritants:No scented sprays, powders, or tight clothing that trap moisture.
- Kegel Exercises:Kegel exercises strengthen pelvic muscles which support healthy circulation around reproductive organs.
- Keeps Pads Handy:If needed use unscented panty liners for comfort without causing irritation but change frequently.
Monitoring symptoms daily ensures you catch any abnormal changes early enough for intervention if necessary.
The Timeline: What Happens After Increased Discharge at 37 Weeks?
Increased vaginal discharge signals that things are progressing toward labor but doesn’t pinpoint exactly when it will start. Here’s what generally unfolds next:
- The cervix continues softening and thinning over days to weeks after increased mucus production begins.
- You might notice intermittent contractions called Braxton Hicks tightening around this time—irregular but preparing muscles for real labor.
- The mucus plug might be lost gradually over several days or all at once (“bloody show”). This typically signals labor within one to two weeks but varies widely among women.
- If membranes rupture spontaneously (water breaks), active labor usually starts soon after within hours up to a day maximum due to infection risk once exposed internally.
Patience combined with awareness makes these final stages manageable rather than stressful.
A Quick Reference Table: Signs Leading from Increased Discharge Toward Labor Onset
| Sign/Event | Description/Effect on Discharge | Labor Timing Estimate |
|---|---|---|
| Cervical Effacement & Dilation Begins | Mucus plug loosens causing thicker/more abundant clear/milky discharge mixed with blood streaks (“bloody show”) | A few days to two weeks later on average |
| Braxton Hicks Contractions | No direct effect on discharge but indicates uterus preparing for labor | Irrregular tightening days/weeks before true contractions begin |
| Mucus Plug Loss | Larger amounts of thick mucous discharged often tinged red/pink/brown | Labor typically within one week though not guaranteed |
| Bursting of Membranes (“Water Break”) | Sudden gush or continuous leaking of clear fluid different from usual mucous secretions | Labor usually starts within hours if not already underway |
The Importance of Regular Prenatal Checkups During Late Pregnancy Changes
At 37 weeks pregnant increased discharge deserves attention during prenatal visits so your healthcare provider can assess whether everything looks normal. They will likely check:
- Cervical status via physical exam—checking dilation/effacement progress;
- Description of your symptoms including nature/amount/color/odor of any discharged fluid;
- Possible swabs for infection screening if abnormalities suspected;
- An ultrasound scan if needed—to assess amniotic fluid volume;
Regular monitoring helps ensure safe progression toward delivery while avoiding surprises like premature rupture of membranes or undiagnosed infections.
