Pregnancy Discharge – characteristics and causes

Discharge at the beginning of pregnancy and during the following months is not unusual and should not cause concern for expectant mothers. It protects the internal female reproductive tract and the developing fetus from infections. Physiologically, the mucus is moderate in amount, whitish or transparent, odorless, and of uniform consistency.

Brown pregnancy discharge or greenish pregnancy discharge can be caused by a number of factors, both physiological and pathological. If there are changes in the amount of discharge, its odor, texture, or if itching or burning occurs, you should consult a doctor. This may be the first sign of an infection within the reproductive tract, which in some cases can be dangerous for the fetus.

Characteristics and Causes of Pregnancy Discharge

Discharge in the first weeks of pregnancy should be odorless, of uniform consistency, white-transparent or slightly yellowish in color. Only the amount of secretion changes. An increase in the concentration of estrogen and progesterone leads to increased production, which enhances the protective function against viruses, bacteria, and fungi.

White discharge during pregnancy with a cottage cheese–like consistency may indicate a fungal infection. Additional symptoms of such an infection include redness around the vaginal opening, itching, and burning. This infection is caused by yeast.

Green discharge during pregnancy, as well as a green-yellow, foamy consistency, indicates an infection with Trichomonas vaginalis. This protozoan can cause a bladder infection accompanied by whitish urine, pain in the urethral area during urination, burning, and stinging sensations.

Brown discharge during pregnancy means that the vaginal discharge is tinged with blood. However, this does not necessarily indicate something dangerous, so you should not panic. In early pregnancy, physiological spotting may occur as a result of embryo implantation in the uterine wall, after sexual intercourse, and due to hormonal changes in the body as it prepares for pregnancy and subsequent childbirth.

After fertilization, there is a sudden increase in progesterone concentration, which is intended to protect the embryo and provide optimal conditions for further development. However, the appearance of brown or bloody discharge should never be ignored. You should immediately consult a doctor to determine the exact cause of the discharge mentioned above. To assess the condition of the fetus, an ultrasound examination is performed first. Possible pathological causes of brown discharge include cervical cancer or cancer of the adnexa, placenta previa (i.e., the placenta located over the entrance to the birth canal rather than in the uterine fundus), premature placental separation, and the onset of miscarriage. To avoid serious complications, it is necessary to consult a gynecologist, adopt a restful lifestyle, and follow appropriately selected pharmacological therapy.

Discharge with a characteristic, unpleasant odor indicates a bacterial infection. These are caused by aggressive bacteria. Apart from the specific odor, the color, consistency, and amount resemble normal discharge.

Treatment of a Bacterial Infection

In every case, it is important to determine the exact cause of the infection. Depending on the diagnosis and the pathogenic microorganism, the most appropriate and safest drug therapy is selected. To identify the pathogen, culture tests, bacteriological and mycological swabs, as well as cytology and assessment of vaginal purity (biocenosis) are performed. If an infection threatens the pregnancy, antibiotic therapy becomes necessary. Treatment is less dangerous and easier in the first trimester of pregnancy, but it can be associated with a number of serious complications that may become apparent after the baby is born.

To prevent infections, particular attention should be paid to daily intimate hygiene and keeping the perineal area clean. This can be ensured by wearing cotton underwear that allows good skin ventilation, washing the perineal area from the vaginal opening toward the anus, avoiding tight clothing such as leggings and tight briefs, and avoiding direct exposure of the perineum to hot water, as this can alter vaginal pH and disrupt the natural bacterial flora. Perfumed soaps and perfumed toilet paper should also be avoided. It is beneficial for intimate hygiene products used during pregnancy to contain lactic acid.
