Yellow Discharge During Pregnancy: Causes And Is It Normal?

Having a yellow discharge during your pregnancy is not a healthy sign. In fact, when this occurs at any time during your pregnancy, you should be seeing your doctor as soon as possible since the most likely cause would be an infection.

A light yellow discharge can start early in pregnancy or even in the third trimester. When it is greenish yellow, you are likely to have an infection. But what does an odorless thick yellow-brown mucus in pregnancy indicate?

Is light yellow discharge normal during pregnancy?

The answer to this question is that it is not normal to have a yellow discharge during your pregnancy. Even when you are not pregnant, a yellow discharge is also not a normal observation. This is because, while all other colors of thedischarge may be simple processes of the body, a yellow discharge points to an infection or the side effects of a drug you may be taking.

Other discharge colors such as white, cloudy, brown pink and reddish pink can all be normal before, during and after pregnancy. A yellow discharge, on the other hand, will be most likely a sign that something is wrong.

It is especially problematic when you are pregnant given that most problems of the female reproductive system pose a real danger to your pregnancy. This is because most problems such as infections can easily develop and affect the growing fetus leading to miscarriage, premature birth and other such issues. Indeed, a yellow discharge in your pregnancy warrants a visit to the doctor no matter what stage of the pregnancy you are in.

What causes a yellow discharge during pregnancy?

The normal discharge at any time is a clear to mildly white discharge. However, when it turns yellow or brown in color, it is a sign of an underlying issue that will need the skills of a medical doctor to pinpoint it. When you are pregnant and you notice this change, the need to visit a doctor becomes a matter of urgency.

Among the most common causes of a yellow discharge during pregnancy are;

1. Leukorrhea

Leukorrhea is an odorless (or with a mild odor) and mildly yellow discharge in color. It is a harmless discharge that will be made up of a mixture of normal bacteria, old cells and other secretions from the cervix.

These secretions can be leftovers from the time before you became pregnant. However, due to the increase in the estrogen hormone levels in the body (due to the pregnancy), the discharges would be more.

In such a case, you would have nothing to worry about unless the amount of the discharge is high or it is accompanied by some pain.

2. Yeast infections

Most women have a given amount of yeast which is healthy in nature. This amount of yeast is kept in check by the acid that is released by the lactobacillus bacteria. When there occurs an imbalance in the yeast and the bacteria with the yeast increasing in population, the symptoms of a yeast infection will be observed.

The conditions which can cause a reduction in the bacteria and increase in yeast include;

  • Taking antibiotics which reduce the population of the bacteria.
  • Addition of yeast from a sexual encounter.
  • Taking medications that promote the growth of yeast.

One common symptom of yeast infections is a yellow discharge which can occur whether one is pregnant or not. Other symptoms of a yeast infection include;

  • Rash
  • Pain and soreness
  • itching and irritation
  • Burning sensation during urination and sexual intercourse

3. Bacterial vaginosis

Bacterial vaginosis is a condition in which the normal bacteria overgrow so much that they cause visible symptoms and inflammation. The normal color of the discharge from bacterial vaginosis is from white to yellow to brown. You may also have an itching or burning sensation when you have bacterial vaginosis.

  • Changing a sexual partner
  • Using condoms with irritating chemicals

Some of the most common symptoms of sexually transmitted diseases are discharges of different colors. A yellow discharge can thus be a result of some STDs which need to be checked by a doctor.

Besides the discharge, the most common symptoms of a sexually transmitted disease include the following;

  • Burning sensation
  • Fever

  • Oral herpes
  • Genital herpes

What does a yellow discharge during early pregnancy mean?

When you have a yellow discharge during pregnancy, it can mean many different things the most likely of which are an infection or leukorrhea. To know the exact meaning of each cause of the discharge, here are a few pointers.

1. Yellow odorless discharge when pregnant

When the discharge you have has a yellow color but without any odor, it most likely is leukorrhea. Leukorrhea is often a normal discharge as it presents no threat to you or the baby.

The causes of this discharge are normal bodily sections that mix with dead cells to have a yellow tinge to the discharge. One of the main causes of leukorrhea is the presence and absence of the hormone estrogen. When estrogen levels go up, the amount of the yellow discharge is likely to go up.

While leukorrhea can occur on its own, its color and smell may be influenced by prevailing conditions such as infections and other conditions affecting the female reproductive system.

The amount of discharge when you have leukorrhea is also varied depending on the stage of the pregnancy and the other conditions that affect it. Since it is majorly caused by the estrogen hormone levels, it will also vary as per the estrogen levels.

2. Light yellow mucus, is it a yeast infection?

A light yellow mucus can be a sign of a yeast infection. While the most likely discharge from a yeast infection is cheese white in color, a light yellow mucus can be observed during the early stages of the disease. During this early stages, it can be hard to pinpoint the symptoms of a yeast infection (or any other infection). However, with time, you can see the other symptoms of the disease.

If the thin yellow mucus goes away after a while it may not be an issue to be concerned with. However, if it increases in amount or is coupled with a foul odor, then you need to get checked by your doctor. This is because, during your pregnancy, a lot of changes will be taking place in your body. You might notice some changes that may not be anything to worry about. It is thus advisable to always ask your doctor each time you notice anything strange.

3. Greenish yellow discharge during pregnancy

A green yellow discharge during pregnancy, especially that which has a foul smell and is accompanied by some itching, is often a sign that you have an infection. During your pregnancy, one of the most common infections is yeast.

Given that yeast is already present in about 50 percent of women, it is easy for it to grow out of hand to lead to pain and discomfort. This can occur when the balance between the healthy bacteria and the yeast is upset by medications, a compromised immune system, or introduction of more yeast into the genital area through sexual intercourse.

A yeast infection needs to be treated as fast as possible since it can have dire medical consequences on you and the baby if left untreated.

4. Yellow brown discharge

A yellow brown discharge during pregnancy can be caused by various aspects some of which are normal while others are not. For example, you may have the yellow brown discharge if you had sex that was rough. This is referred to as postcoital bleeding and it is nothing to worry about. Also, given the increased sensitivity of the reproductive organs during this period, any disturbance to the pelvic area may lead to light spotting.

Besides postcoital bleeding, a yellow brown discharge can also due to an infection such as yeast, trichomoniasis, chlamydia, syphilis and others. If it is an infection, the yellow brown discharge will rarely occur in isolation. Other symptoms will also occur.

5. Thick yellow discharge in pregnancy

  • Trichomoniasis
  • Candidiasis
