A healthy vaginal discharge is clear or milky white and odorless (or with a mild odor). The varying amount of vaginal discharge depends on whether you are menstruating, pregnant, or going through menopause (1) (2). Increased estrogen levels may cause watery discharge during pregnancy, although this is not worrisome. However, if there are any color changes and a foul smell or other symptoms, it can be concerning (3). Read on to learn more about watery discharge while pregnant, why it happens and how to manage it.

What Is Watery Discharge During Pregnancy?

During pregnancy, as your body is preparing to accommodate your baby, your cervix and the vaginal walls soften, causing an increase in estrogen levels. This leads to increased blood flow in the pelvic region, which stimulates the body’s mucous membranes, causing watery discharge. Pregnant women are more prone to infections, and therefore, the increased watery discharge can protect your vagina from the entry of viruses and bacteria. It clears out the dead cells in the vagina (3). This discharge might get heavier with the advance of your pregnancy, and you may even confuse it with urine. However, understand that it is normal. An increase in discharge is also one of the early pregnancy symptoms, but it might not be the same in all cases. Therefore, you should look for other symptoms and take a pregnancy test (4).

How Does A Watery Discharge Appear?

During pregnancy, the watery discharge appears clear or milky white, with a thin consistency, and is called physiologic leucorrhea. The discharge may either have a mild smell or no odor and resembles the vaginal discharge that you have before your periods. You might feel it in your underwear (5).

Is Having A Watery Discharge During Pregnancy Normal?

Having a watery discharge during pregnancy is a normal occurrence, and rarely a cause of concern. It also indicates that your body is working hard to keep you and your baby safe throughout the pregnancy. Towards the end of your third trimester, the watery discharge increases and may also include blood and mucus called a ‘show.’ This indicates your body is going into labor within a few days (5) (6).

What Are The Causes Of Watery Discharge In Pregnancy?

Pregnancy-related changes in the vagina and cervix Increased estrogen levels Rupture of the amniotic sac (water breaking) at the beginning of or during labor (6) Amniotic fluid leakage or premature rupture of membranes (PROM) (7)

When Is Watery Discharge A Sign Of Concern?

If you have a vaginal discharge other than clear, milky or thin, it could cause concern. The associated symptoms and unusual changes may need a doctor’s attention (4).

Foul or strong, fishy smell Vaginal itchiness or soreness Burning sensation Change in the color of vaginal discharge to yellow, brown, pink, curdy white, or any other color Change in the consistency of the discharge

These symptoms and changes could indicate vaginal infections, including bacterial infection (vaginosis), parasitic infection (trichomoniasis), yeast infection (candidiasis), or sexually transmitted infection. Since these infections can cause various pregnancy complications, ensure to consult your doctor as soon as you notice any of these symptoms (8). You should also seek immediate medical care if you observe a heavy gush of watery fluid at the end of your pregnancy (i.e., water breaking) (6). A clear watery discharge with cramps in the lower abdomen also necessitates medical intervention as it could signify pelvic inflammatory disease (PID) (9).

How To Manage Watery Discharge When Pregnant?

Since watery discharge during pregnancy is not a cause of concern, it requires no treatment prevention. However, the following measures can help prevent heavy and abnormal watery discharge during pregnancy (10) (11):

Wear cotton underpants, panty liners, or pads as per your convenience (5) Avoid wearing tight clothing, such as tight pants or bikini shorts, for a longer time Wipe your butt from front to back after the toilet use If you have irritation in your genital area, change your detergent Avoid hot tubs and feminine hygiene sprays, as these can cause irritation Maintain good hygiene by taking a bath everyday

Avoid using tampons and douching as they may introduce unwanted germs Some birth control measures can also irritate some women; therefore, consult your health care provider if you notice any such symptoms.

You may have a steady trickle flow or gush of amniotic fluid when your water breaks, but it is PROM if you see the above signs before your due date (i.e., before the 37th week) (7).
