5 Causes of Yellow Discharge During Pregnancy

A yellowish vaginal discharge during pregnancy can be worrying, especially if it has an unpleasant odor. This type of vaginal discharge is common, particularly between the first and fourth months of pregnancy. Some women even notice it after they give birth. The cause for this type of discharge is the irregular secretion from the cervix due to hormonal changes. Although this discharge can be quite normal, it’s important to see your doctor to make sure there are no complications.

Here are some of the most common reasons you might have a yellowish discharge during pregnancy.

Normal vaginal secretions

Your vagina normally produces fluid that keeps it clean and moisturized for everyday life. You may notice this fluid as a vaginal discharge. It’s normal for there to be more of it when you are pregnant because your body releases extra amounts of estrogen, which boosts the number of vaginal secretions. If you have never noticed vaginal secretions before now, you might notice them during your pregnancy. However, if they are accompanied by itching, burning, or irritation, then there may be a problem.

Vaginal infection

If you have a vaginal infection, the secretions from your cervix will often change color to yellow or green, and it will have an unpleasant odor. A number of different types of infections can cause these symptoms during pregnancy. These include bacterial vaginosis, trichomoniasis, vaginal yeast infection, and sexually transmitted infections.

Changes in your cervix

The type of cervical mucus you have throughout the month is different from the mucus during pregnancy. There’s a thicker layer of mucus on your cervix early in pregnancy so that the sperm can’t reach an egg easily if they are still present after you ovulate. This mucus is usually yellow or cloudy in appearance, but it can change color during pregnancy. It will often become increasingly white and thick when you are ready to give birth.

Normal vaginal discharge

After giving birth Some women notice that they have a whitish vaginal discharge shortly after they’ve given birth. They might also have a yellow vaginal discharge with an unpleasant odor. This is normal and it’s the body’s way of ridding itself of any leftover blood or mucus from childbirth. However, if the vaginal discharge is excessive, then you should see your doctor immediately.

Vaginal bleeding

If you notice that there is bright red blood mixed in with the yellow vaginal discharge, then you could be having vaginal bleeding. You might see this bleeding as you wipe yourself after urinating or passing a bowel movement. If you notice any bright red blood during your pregnancy, it’s important to call your doctor immediately because it may be due to placenta previa. This is when the placenta partially or totally covers the cervix.


If you notice any types of abnormal vaginal discharge during your pregnancy, it’s important to contact your doctor immediately. Your doctor will be able to determine the cause and prescribe treatment if necessary.
