Vaginal discharge is normal, and most people produce between 1 and 4 milliliters per day, roughly half a teaspoon to a full teaspoon. If you’re noticing more than usual, the cause is almost always hormonal shifts, a phase of your menstrual cycle, or a change in your body like pregnancy or a new medication. Less commonly, increased discharge signals an infection that needs treatment.
What Normal Discharge Looks Like
Healthy discharge is produced by glands in your cervix and vaginal walls. It serves a purpose: flushing out dead cells and bacteria, keeping your vaginal pH in the acidic range of 3.8 to 4.5, and protecting against infection. The amount, color, and texture shift throughout the month, so what looks “normal” on day 7 of your cycle won’t match what you see on day 20.
Clear, white, or slightly off-white discharge with no strong smell is typical. It can feel slippery, sticky, or creamy depending on where you are in your cycle. Some people consistently produce more than others, and that baseline varies widely. If the volume has always been on the higher side and there’s no odor, itching, or color change, it’s likely just how your body works.
How Your Cycle Changes Discharge
Estrogen is the main driver. As estrogen rises, it increases the permeability of cervical cells, essentially making the tissue more flexible and allowing more fluid to pass through. This is why discharge ramps up noticeably in the days leading to ovulation.
On a typical 28-day cycle, here’s what to expect:
- Days 1 to 4 (after your period): Dry or tacky, white or slightly yellow.
- Days 4 to 6: Sticky, slightly damp, white.
- Days 7 to 9: Creamy, yogurt-like, wet and cloudy.
- Days 10 to 14 (around ovulation): Stretchy, slippery, and clear, often compared to raw egg whites. This is the peak volume, lasting about three to four days.
- Days 15 to 28: Dry or nearly dry until your period starts.
If you’re noticing a lot of discharge and it’s clear, stretchy, and wet, check where you are in your cycle. You may simply be ovulating. That egg-white consistency is your body’s way of creating an environment that helps sperm travel, and it’s one of the most common reasons people suddenly notice more fluid than usual.
Pregnancy and Hormonal Shifts
Pregnancy causes a significant and sustained increase in discharge. Higher levels of both estrogen and progesterone boost blood flow to the pelvic area and ramp up secretion from the cervical glands. The result is a thin, clear or white, mild-smelling discharge called leukorrhea that can start early in the first trimester and continue throughout pregnancy. Many people notice this increase before they even get a positive test.
Hormonal contraceptives can also change your baseline. Birth control pills, patches, and hormonal IUDs alter estrogen and progesterone levels, which can increase or decrease the amount of discharge you produce. If you recently started or switched contraception and noticed a change, that’s a likely explanation. The shift usually stabilizes after a few months as your body adjusts.
Sexual Arousal
Physical arousal triggers its own separate source of fluid. Small glands near the vaginal opening, called Skene’s glands, swell in response to increased blood flow during arousal and release a lubricating, milk-like fluid. Some people also produce noticeable fluid during orgasm. This is distinct from cervical discharge and happens on top of whatever your baseline is for the day, so it can make the total volume seem much higher than expected. It contains antimicrobial properties that help protect against infection.
Infections That Increase Discharge
When discharge changes color, smell, or texture in ways that don’t match your usual cycle pattern, an infection is the most common culprit. Three infections account for the vast majority of cases.
Bacterial Vaginosis
BV is the most common vaginal infection in reproductive-age adults. It happens when the balance of bacteria in the vagina shifts, raising the pH above 4.5. The hallmark is a thin, milky, grayish-white discharge with a fishy odor that often gets stronger after sex. It’s not sexually transmitted, though sex can trigger it. Douching, scented soaps, and bubble baths can also disrupt the bacterial balance and set it off.
Yeast Infections
A yeast infection produces thick, white, clumpy discharge that’s often compared to cottage cheese. It typically doesn’t have a strong odor, but it comes with intense itching and sometimes burning or redness around the vulva. Antibiotics are a common trigger because they kill off protective bacteria along with the targeted infection, giving yeast room to overgrow. Steroids, diabetes, and pregnancy also raise the risk.
Trichomoniasis
Trichomoniasis is a sexually transmitted infection caused by a parasite. The discharge is frothy, yellowish or greenish, and has a fishy smell. It often comes with irritation, burning during urination, and discomfort during sex. Unlike BV, trich requires treatment for both you and your sexual partner to prevent reinfection.
Other Factors That Affect Volume
Several everyday things can increase discharge without signaling a problem. Exercise and physical activity increase blood flow to the pelvic area, which can temporarily boost secretion. Stress affects hormone levels, and even changes in diet or hydration can subtly alter discharge. Irritants like scented laundry detergent, latex condoms, or spermicidal gels can trigger excess fluid production as the vaginal tissue reacts to the irritation.
Antibiotics deserve special mention. While they treat infections elsewhere in the body, they can disrupt vaginal flora and lead to either a yeast infection or BV as a secondary effect. If you’ve recently finished a course of antibiotics and notice a change, that connection is worth noting.
Signs That Something Is Off
Volume alone isn’t usually the concern. What matters more is what the discharge looks like and what symptoms come with it. Watch for these changes:
- Color shift: Green, bright yellow, or gray discharge is not part of a normal cycle.
- Texture change: Thick and clumpy (cottage cheese) or frothy and bubbly.
- Strong odor: A persistent fishy or foul smell, especially one that worsens after sex.
- Itching or burning: Around the vagina or vulva, especially if the skin looks red or irritated.
- Bleeding or spotting: Outside of your regular period, particularly if it accompanies unusual discharge.
Any combination of these warrants a visit to a healthcare provider. Most vaginal infections are straightforward to diagnose and treat, but they don’t reliably resolve on their own, and leaving BV or trich untreated can lead to complications over time. If your discharge is simply higher in volume but looks, feels, and smells the way it always has, your body is almost certainly doing exactly what it’s supposed to do.
