Increased vaginal discharge at 33 weeks pregnant is usually normal but should be monitored for signs of infection or labor.
Understanding Vaginal Discharge at 33 Weeks Pregnant
At 33 weeks pregnant, your body is undergoing significant changes to prepare for childbirth. One of the most common experiences during this time is an increase in vaginal discharge. This discharge, medically known as leukorrhea, is a natural response triggered by hormonal shifts and increased blood flow to the pelvic area. It typically appears as a thin, milky-white or clear fluid with a mild odor or no odor at all.
The primary function of this discharge is to keep the vagina clean and prevent infections by flushing out harmful bacteria. The cervix also produces mucus that thickens during pregnancy to form a protective barrier called the mucus plug, which helps shield the uterus from bacteria.
While increased discharge at 33 weeks pregnant is generally normal, it’s crucial to distinguish between harmless changes and those that may signal complications such as infections or preterm labor. Paying attention to color, consistency, odor, and accompanying symptoms can help you identify when medical advice is necessary.
Causes of Increased Discharge at 33 Weeks Pregnant
Several factors contribute to the rise in vaginal discharge during late pregnancy:
1. Hormonal Changes
Estrogen levels surge throughout pregnancy, especially in the third trimester. This hormone stimulates the mucous membranes in the cervix and vagina, increasing secretions. The extra fluid helps maintain a healthy environment in the birth canal.
2. Increased Blood Flow
Blood flow to the pelvic region intensifies as your body prepares for labor. This causes tissues in the vagina and cervix to swell slightly and produce more mucus.
3. Cervical Mucus Plug Formation
Around this stage, your body continues producing cervical mucus that accumulates into a plug sealing off the uterus from external contaminants.
4. Physical Activity and Sexual Intercourse
Both can temporarily increase vaginal secretions due to stimulation or mild irritation of vaginal tissues.
5. Approaching Labor
As you near delivery, discharge may become heavier or develop streaks of blood (known as “bloody show”), signaling cervical dilation.
Types of Discharge and What They Mean
Not all discharges are created equal—understanding their characteristics can help you determine if what you’re experiencing is typical or requires attention:
| Discharge Type | Description | Possible Cause/Action |
|---|---|---|
| Clear or White Thin Mucus | Milky or watery texture with no strong odor. | Normal pregnancy discharge; no cause for concern. |
| Thick, Clumpy White (Cottage Cheese-Like) | Thickened texture with itching or irritation. | Candidiasis (yeast infection); see a healthcare provider. |
| Yellow or Greenish with Foul Odor | Pungent smell often accompanied by itching or burning. | Bacterial vaginosis or other infections; requires medical treatment. |
| Pink or Bloody Streaks (Bloody Show) | Mucus mixed with light blood streaks. | Cervical dilation signaling labor onset; notify your doctor. |
| Watery and Excessive Leakage | Sudden gush or slow leak of clear fluid. | POSSIBLE amniotic fluid leak; urgent medical evaluation needed. |
When Increased Discharge Signals a Problem at 33 Weeks Pregnant
Although increased discharge is mostly harmless, certain changes demand immediate attention:
- Suspicious Color: Yellow-green discharge with unpleasant odor often indicates infection.
- Irritation and Itching: Persistent discomfort could mean yeast infection or bacterial vaginosis.
- Bloody Discharge: Bright red bleeding isn’t typical outside of bloody show and requires prompt assessment.
- Sudden Fluid Leakage: A gush of clear fluid might be amniotic fluid leaking from ruptured membranes—a potential emergency.
- Painful Contractions Accompanying Discharge: Could indicate preterm labor needing immediate care.
- Fever or Chills With Discharge: Suggests infection spreading beyond local tissues; seek urgent help.
- A Change in Volume: A sudden spike in watery discharge might mean membrane rupture rather than normal leukorrhea.
- An Unusual Odor: Strong fishy smell often accompanies bacterial infections like bacterial vaginosis.
If any of these signs appear alongside increased discharge at 33 weeks pregnant, contact your healthcare provider immediately.
The Role of Hygiene and Lifestyle in Managing Discharge
Maintaining good hygiene habits can minimize discomfort from increased vaginal secretions without disrupting natural protective mechanisms:
- Avoid douching: It disturbs natural vaginal flora and increases infection risk.
- Select breathable underwear: Cotton fabrics allow air circulation and reduce moisture buildup.
- Avoid tight clothing: Restrictive garments trap heat and moisture promoting bacterial growth.
- Mild soap only: Use gentle cleansers without fragrances around external genitalia; avoid internal washing.
- Avoid scented products: Perfumed sprays, powders, or wipes can irritate sensitive tissues during pregnancy.
- Kegel exercises: Strengthening pelvic floor muscles supports circulation and reduces swelling contributing to excessive secretions.
Practicing these habits helps keep discharge manageable while supporting overall vaginal health during late pregnancy.
Treatment Options for Abnormal Discharge During Late Pregnancy
If abnormal discharge occurs due to infection or other complications, treatment depends on diagnosis:
Bacterial Vaginosis (BV)
BV results from an imbalance in vaginal bacteria leading to overgrowth of harmful species like Gardnerella vaginalis. Symptoms include grayish-white discharge with fishy odor.
Treatment involves prescribed antibiotics such as metronidazole either orally or as a topical gel safe during pregnancy.
Candidiasis (Yeast Infection)
Yeast infections cause thick white clumpy discharge accompanied by itching and redness. Antifungal medications like clotrimazole creams are commonly recommended by doctors during pregnancy.
Ampniotic Fluid Leak (Premature Rupture of Membranes)
If your membranes rupture prematurely causing fluid leakage before labor onset, hospitalization may be necessary for monitoring fetal well-being and preventing infection.
Medical teams might administer steroids to accelerate fetal lung maturity if early delivery seems likely.
Treatment Precautions During Pregnancy
Always consult your obstetrician before using any medication for vaginal infections while pregnant since some drugs aren’t safe during gestation.
Never self-medicate based on internet research alone—misdiagnosis could lead to improper treatment affecting both mother and baby’s health.

Frequently Asked Questions
Is increased discharge at 33 weeks pregnant normal?
Yes, increased vaginal discharge at 33 weeks pregnant is usually normal. It is caused by hormonal changes and increased blood flow as your body prepares for childbirth. This discharge helps keep the vagina clean and prevents infections.
What does increased discharge at 33 weeks pregnant indicate about labor?
Increased discharge near 33 weeks can sometimes signal approaching labor, especially if it becomes heavier or contains streaks of blood known as “bloody show.” This indicates cervical dilation and should be discussed with your healthcare provider.
When should I be concerned about increased discharge at 33 weeks pregnant?
If the discharge has a strong odor, unusual color, causes itching or irritation, or is accompanied by pain or fever, it may indicate an infection. In such cases, contact your healthcare provider promptly for evaluation and treatment.
How do hormonal changes affect increased discharge at 33 weeks pregnant?
At 33 weeks pregnant, rising estrogen levels stimulate the mucous membranes in the cervix and vagina to produce more secretions. This increase in discharge supports a healthy birth canal environment and protects against infections.
Can physical activity cause increased discharge at 33 weeks pregnant?
Yes, physical activity and sexual intercourse can temporarily increase vaginal discharge at 33 weeks pregnant. These activities may mildly irritate vaginal tissues or stimulate secretions, which is generally harmless unless other symptoms develop.
The Connection Between Increased Discharge and Preterm Labor at 33 Weeks Pregnant
One concern linked with increased vaginal secretions late in pregnancy is preterm labor—labor beginning before 37 completed weeks gestation. While many women experience benign increases in discharge near term due to cervical changes, certain patterns hint at premature contractions:
- A sudden increase accompanied by pelvic pressure or cramping may indicate early cervical dilation.
- The presence of bloody show signals that labor might be imminent within days or hours depending on individual circumstances.
- A gush of watery fluid could mean rupture of membranes triggering labor onset prematurely if not close enough to term yet.
Monitoring these signs closely alongside any increase in vaginal secretions ensures timely intervention when necessary. Obstetricians often recommend bed rest, hydration, medications like tocolytics (to suppress contractions), or steroids for lung development when preterm labor threatens fetal health.
