Mucus discharge at 37 weeks is a normal sign your body is preparing for labor but sudden changes may require medical attention.
The Nature of Mucus Discharge at 37 Weeks Pregnant
At 37 weeks pregnant, your body is entering the final stretch before delivery. One of the most common and noticeable changes during this time is an increase in vaginal mucus discharge. This discharge, often called the “mucus plug,” serves as a protective barrier inside the cervix, sealing off the uterus from bacteria and infections throughout pregnancy.
As you approach labor, the cervix begins to soften, thin out (efface), and dilate in preparation for childbirth. This process causes the mucus plug to loosen and eventually expel. The discharge you notice at 37 weeks pregnant can be thick, sticky, clear, or slightly pinkish or brownish due to small blood vessels breaking during cervical changes.
Understanding this discharge helps differentiate between normal bodily functions and signs that might indicate complications. It’s important to recognize that while mucus discharge is generally expected at this stage, significant changes in color, odor, or consistency should prompt a consultation with your healthcare provider.
Why Does Mucus Discharge Increase at 37 Weeks?
The increase in mucus discharge near full term happens because your cervix is undergoing crucial transformations. The cervix is composed mostly of collagen fibers that maintain its firmness during pregnancy. As hormonal shifts occur—especially rising levels of estrogen and prostaglandins—the collagen softens and the cervix starts to dilate slowly.
This softening causes the mucus plug to detach gradually, releasing mucus mixed with cervical cells and sometimes traces of blood. The discharge acts as a natural signal that your body is gearing up for labor within days or weeks. For many women, this can happen suddenly or over several days with varying amounts of mucus released intermittently.
Besides hormonal influence, physical activity or sexual intercourse can sometimes stimulate cervical changes leading to more noticeable mucus discharge. It’s also common for women to experience increased vaginal secretions during late pregnancy due to enhanced blood flow and lubrication of vaginal tissues preparing for delivery.
Characteristics of Normal Mucus Discharge
- Color: Clear, white, off-white, or slightly pink/brown-tinged
- Consistency: Thick, sticky, gelatinous
- Amount: Moderate; can vary from light spotting to heavier thick discharge
- Odor: Mild or no distinct smell
Any drastic deviations from these characteristics could signal infection or other issues requiring medical evaluation. For example, greenish-yellow discharge with foul odor might indicate bacterial vaginosis or other infections.
The Mucus Plug vs. Other Types of Discharge
It’s vital to distinguish between normal mucus plug discharge and other types of vaginal fluids you might experience near term:
Mucus Plug Discharge
This is thick mucus mixed with cervical cells and sometimes streaks of blood (known as “bloody show”). It often appears jelly-like and may come out in chunks or strings over hours or days.
Ampullary Fluid or “Show”
Close to labor onset, some women notice increased watery discharge mixed with mucus — this can be amniotic fluid leaking if membranes have ruptured (water breaking). Amniotic fluid tends to be clear or pale yellow without odor.
Cervical Fluid Changes
Throughout pregnancy, cervical secretions fluctuate in volume and texture due to hormonal shifts but typically remain odorless and clear.
Distinguishing these helps avoid confusion about when labor truly begins versus normal pre-labor symptoms.
Mucus Discharge Patterns at 37 Weeks Pregnant
Every woman’s experience varies widely but here are common patterns seen with mucus discharge around week 37:
- Sporadic Release: Small amounts of thick mucus over several days as cervix gradually effaces.
- Bloody Show: Pinkish or brown-tinged mucus signaling minor cervical capillary rupture.
- Larger Plug Expulsion: A more substantial chunk of mucus expelled suddenly.
- No Noticeable Change: Some women may not see obvious mucus loss until active labor begins.
The timing between noticing these signs and actual labor onset varies — it could be hours or even up to two weeks.
The Role of Cervical Dilation and Effacement
Your healthcare provider will often check your cervix during prenatal visits after week 36 to assess dilation (opening) and effacement (thinning). These measurements correlate closely with how much mucus discharge you might expect.
| Cervical Status | Mucus Discharge Description | Possible Labor Timeline |
|---|---|---|
| No dilation/effacement | No significant mucus loss; cervix still sealed tightly. | No imminent labor; could still be days/weeks away. |
| Slight effacement (30-50%) & dilation (1-2 cm) | Sporadic thick mucous; possible light bloody show. | Labor may start within a few days/weeks. |
| Moderate effacement (60-80%) & dilation (3-4 cm) | Larger amounts of mucous plug lost; frequent bloody show possible. | Labor likely imminent within hours/days. |
| Full effacement & dilation (>4 cm) | Mucous plug usually fully expelled; active labor signs present. | Labor underway or starting soon. |
This table helps visualize how cervical changes relate directly to mucus discharge patterns.

Frequently Asked Questions
What does mucus discharge at 37 weeks pregnant indicate?
Mucus discharge at 37 weeks pregnant is a normal sign that your body is preparing for labor. It usually comes from the mucus plug loosening as the cervix softens and begins to dilate. This discharge can be clear, sticky, or slightly pinkish due to small blood vessels breaking.
Is it normal for mucus discharge to increase at 37 weeks pregnant?
Yes, an increase in mucus discharge at 37 weeks pregnant is common. Hormonal changes cause the cervix to soften and release the mucus plug, resulting in more noticeable vaginal secretions. This process signals that labor may be approaching within days or weeks.
When should I be concerned about mucus discharge at 37 weeks pregnant?
You should consult your healthcare provider if the mucus discharge has a strong odor, unusual color (green or yellow), or is accompanied by heavy bleeding or severe pain. These signs might indicate infection or other complications requiring medical attention.
Can physical activity affect mucus discharge at 37 weeks pregnant?
Physical activity and sexual intercourse can sometimes stimulate cervical changes, leading to increased mucus discharge at 37 weeks pregnant. This is generally normal, but if you notice sudden heavy bleeding or severe discomfort, contact your healthcare provider immediately.
What color and consistency of mucus discharge is typical at 37 weeks pregnant?
Typical mucus discharge at 37 weeks pregnant is thick, sticky, and gelatinous with colors ranging from clear to white or slightly pinkish/brown-tinged. Variations in amount are normal as the body prepares for labor, but unusual colors or foul smells should be evaluated by a doctor.
Differentiating Between Normal Mucus Discharge and Warning Signs
While some increase in vaginal discharge at 37 weeks pregnant is typical, certain symptoms demand immediate medical attention:
- Sudden gushes of fluid:This might mean your water broke — call your doctor right away.
- Mucus with strong foul odor:This can indicate infection such as bacterial vaginosis or chorioamnionitis which requires treatment.
- Bright red bleeding:
- Persistent itching/burning sensation:
- Mucus accompanied by fever/chills/pain:
- No fetal movement noticed after increased mucous loss:
- Estrogen:This hormone surges toward term increasing blood flow to pelvic tissues making vaginal secretions more abundant and stimulating cervical softening.
- Progesterone:Keeps uterine muscles relaxed throughout pregnancy but declines near term allowing contractions and cervical ripening.
- Prostaglandins:Naturally produced compounds that promote inflammation-like responses softening collagen fibers in cervix leading to dilation and effacement releasing mucous plug.
- Cortisol:A stress hormone increasing near birth triggering fetal lung maturation but also influencing uterine readiness for contractions indirectly affecting cervical status.
- Bacterial Vaginosis/Bacterial Infections:A course of antibiotics prescribed by your obstetrician clears infection safely during pregnancy minimizing risks for mother/baby complications like preterm labor.
- Candidiasis (Yeast Infection):An antifungal medication either topical creams or oral prescribed depending on severity resolves irritation associated with abnormal discharges.
- Semi-Emergency Situations:If membranes rupture prematurely causing watery leakage mixed with mucous without contractions yet—hospital evaluation ensures fetal wellbeing while preventing infection risks via antibiotics/steroid shots if preterm delivery suspected.
- Mild Hygiene Practices:Avoid harsh soaps; use warm water only when cleaning genital area keeping it dry afterwards reduces irritation risk associated with excess moisture from mucous production.
- Cotton Underwear & Breathable Clothing:This allows airflow reducing fungal/bacterial growth potential especially important if secretions increase significantly near term.
- Avoid Douching/Scented Products:Douching disrupts natural flora increasing infection risk while scented sprays/liners irritate sensitive tissues resulting in inflammation mimicking abnormal discharges needing unnecessary intervention.
- Kegel Exercises & Pelvic Floor Relaxation Techniques:Aiding circulation around pelvic organs supports healthy tissue function promoting smoother cervical ripening without undue strain on vaginal walls producing excess secretions due to friction/inflammation from tight muscles.
- If accompanied by regular contractions spaced less than ten minutes apart lasting over one minute each—labor has likely begun actively requiring hospital admission planning immediately;
- If no contractions occur post-discharge but other signs like lower back pain/cramping appear—labor could still be imminent;
- If no further symptoms develop within days after losing the plug—continue monitoring fetal movements closely ensuring no distress occurs;
- Cervical checks measuring dilation/effacement;
- Maternity ultrasounds assessing amniotic fluid levels;
- Nutritional guidance optimizing energy reserves for delivery;
- Lifestyle counseling minimizing stress promoting healthy birth outcomes;
These warning signs help ensure both mother and baby stay safe during late pregnancy.
The Science Behind Hormones Influencing Mucus Discharge at Week 37
Hormones play a starring role in preparing your body for birth—and they directly affect cervical changes causing mucus release:
These hormonal cascades carefully orchestrate each step leading from early pregnancy maintenance into active labor readiness—mucus discharge being one visible outcome.
Treatment Options for Abnormal Mucus Discharge During Late Pregnancy
In most cases where mucus discharge remains normal—clear/sticky without discomfort—no treatment is needed except monitoring symptoms closely.
However, abnormal discharges caused by infections require targeted treatments:
Always consult healthcare professionals before using any medication during pregnancy ensuring safety protocols are followed strictly.
Caring for Yourself When Experiencing Increased Mucus Discharge at 37 Weeks Pregnant
Managing increased vaginal secretions comfortably involves simple self-care strategies:
Taking these steps will help you stay comfortable while monitoring any changes carefully.
The Connection Between Mucus Discharge and Labor Onset Timing
Mucus plug loss doesn’t guarantee immediate labor but strongly signals its approach. Research shows that many women go into labor within one week after losing their mucus plug; however some may deliver sooner while others take longer up to two weeks postpartum expectant period.
Understanding this connection reduces anxiety about waiting times after noticing increased mucous loss:
In summary: Losing your mucus plug signals your body’s readiness but patience remains key until stronger labor signs emerge naturally.
The Role of Healthcare Providers During This Stage of Pregnancy
Prenatal visits become more frequent approaching week 37 allowing providers to monitor maternal/fetal health closely including:
Providers also educate mothers on recognizing danger signs related to abnormal discharges helping reduce emergency situations through timely interventions.
Regular communication between patient/provider ensures any unusual symptom such as excessive bleeding/discolored foul-smelling mucous triggers immediate evaluation preventing complications before they escalate.
Conclusion – 37 Weeks Pregnant And Mucus Discharge
