Why do yellow discharge appear during early pregnancy

Slight and pale discharge of a yellow tint in early pregnancy is usually considered a variant of the norm. Often they appear due to changes in the microflora of the vagina and softening of the walls of the uterus due to the preparation of the body for bearing a child (1).

The following symptoms should be alert:

  • pain,
  • burning,
  • itching,
  • unpleasant odor
  • weakness,
  • temperature rise. 

一 With such symptoms, yellow discharge at any stage of pregnancy most often signals a bacterial infection (STDs, staphylococci, streptococci and others), 一 explains obstetrician-gynecologist Elena Kollerova.- They can cause inflammation in the vagina, cervix, uterus and ovaries, as well as provoke infection of the fetus. 

1 trimester

The body begins to prepare for gestation and childbirth immediately after conception. Hormonal changes occur, the hormone progesterone accumulates. It contributes to the formation of a mucous plug, the main function of which is to protect the uterine cavity from pathogenic microorganisms. It is under the influence of progesterone that a light yellow discharge can appear (2).

In some cases, the separation of the yellow secret indicates the presence of inflammatory processes – thrush, bacterial vaginosis, genital infections, cervicitis and colpitis. The main danger of pathologies during this period is due to the restriction of medications acceptable for treatment: most of them are allowed no earlier than the 12th week. Therefore, if you notice any warning signs, see a doctor as soon as possible.

Why yellow discharge appears during late pregnancy

The appearance of yellow discharge most often may indicate a pathology. As at the beginning of pregnancy, you need to pay attention to the color, character and accompanying symptoms. The emergence of any suspicion is a reason for an early visit to the gynecologist.

2 trimester

In the second trimester of pregnancy, the appearance of yellow discharge is also possible. Their consistency depends on the hormone estrogen. Under its influence, the vaginal secretion becomes more liquid and plentiful. 

Should be alert:

  • darkening of secretions
  • unpleasant odor
  • burning,
  • redness of the mucous membranes,
  • temperature rise.

Such symptoms may indicate inflammatory processes or exacerbation of chronic diseases of the reproductive system.

3 trimester

Light yellow discharge without odor and impurities is usually considered a normal variant in the third trimester. However, they can also appear for other reasons.

  • Leakage of amniotic fluid. It is considered dangerous until 37 weeks, when the baby is still premature.
  • Chorioamnionitis. This is an infection of the amniotic fluid or the inner membranes of the fetus. It is accompanied by high fever and an increased number of leukocytes. The level of the latter is determined by the results of the smear.
  • Removal of the mucous plug. It is considered one of the main harbingers of childbirth.

A timely trip to the gynecologist will help protect yourself and your unborn child. If necessary, the doctor will refer you for an examination and prescribe the appropriate treatment.
