Pink discharge: does it indicate pregnancy? See the causes

Going to the gynecological consultation periodically is one of the necessary precautions for women’s health. But, on a daily basis, it is important to pay attention to signs that may indicate an abnormal condition.

For example, a vaginal discharge may be natural, but it may also indicate some other pathological condition.

When accompanied by some other symptom, it can signal the presence of an inflammation, uterine disease or even a possible pregnancy.

In the following text we will talk about a specific type of discharge, the pinkish, which is a vaginal discharge with the presence of very little blood.

Continue reading to understand the possible causes!


What can be the pink discharge?

The pink discharge can have different causes, but it is very associated with the beginning of a pregnancy, and can be a nidation , that is, the bleeding that occurs when the fertilized egg implant in the uterine wall. It may also be related to the use of medications, hormonal changes, injuries, missed periods and illnesses.

First, it is important to understand that discharge is something natural in a woman’s body.

It is a mucus produced by the glands present in the genital region. Its function is to expel dead cells, protect the woman’s uterus from bacteria and provide lubrication of the vaginal canal, important so that there is no pain during intercourse with penetration.

When it is a white or transparent discharge with no strong smell, itching, pain, burning or any other symptom, it is considered normal.

This is not the case with the pink discharge, which represents the presence of blood in the mucus. It can be a lighter or more intense pink, depending on the amount of blood expelled together.

In this case, the main causes are:

Hormonal variations

Changes in hormone levels can interfere with a woman’s menstrual cycle and vaginal discharge. Although it is not the most common cause of pink discharge, it can be one of the associated factors.

For example, there are women who notice a slight pinkish bleeding in some cycles, during the period of ovulation.

Ovarian cyst

Ovarian cysts are small pockets of fluid that form in the ovaries. They are not always worrying, as they can disappear on their own – without treatment. However, when they persist, it is important to consult specialists and assess the need for treatment.

The condition does not usually cause significant symptoms, but it can trigger cramps, pain and bleeding, in addition, there are signs that can be related, such as irregular menstruation and severe cramps.


Women who use contraceptives with a break can, due to hormonal changes, escape before the expected period.

It is more common to occur in those who are starting to take the medication, as the body is still getting used to the hormonal doses received.

In such cases, brown discharge is more common, but it is possible that a more red or pink discharge may occur.


When a fertilized egg is implanted in the uterine wall, a small pink bleed may occur. This bleeding is called nidation and is usually the first sign of pregnancy.

It often goes unnoticed by being mistaken for menstruation. Therefore, the woman who wants to become pregnant needs to be aware of the symptoms and know how to recognize the nesting.

Pink discharge can also be a symptom of ectopic pregnancy , that is, when the egg is fertilized outside the uterus.

Uterine infections and diseases

Infections caused by bacteria, viruses and fungi can also cause pink bleeding. Usually, in these cases, discharge is not the only sign. It is also common to have a bad smell, pain, itching and other symptoms.

Other causes involve possible diseases in the uterine region, menopause and also gynecological exams, which can cause some injury if performed incorrectly by the professional.

Sexual intercourse

A pink discharge after intercourse may indicate that there has been some injury or trauma to the vaginal canal, causing a blood vessel to rupture and causing a small bleed.

It is important to always be aware of possible cervical injuries when there is bleeding during or shortly after intercourse.

Pink discharge with odor (strong smell): what can it be?

The discharge, pink or with another color, accompanied by a strong odor can indicate the presence of a more serious health problem and requires an investigation with a doctor. It may be a sign of an infection, including sexually transmitted infections (chlamydia and gonorrhea , for example).

In these cases, in addition to the bad smell, other symptoms may appear, such as pain, itching and burning.

Light pink discharge: is it normal?

In general, yes. Usually, the occurrence of light pink discharge can be related to small menstrual leaks (then the blood mixes with the vaginal mucus, making it pink) or to small lesions in the vaginal mucosa after intercourse.

It is also possible that the pink discharge is related to pregnancy, but it is important to pay attention to the duration and intensity of this discharge.

Hormonal changes may be related as well. In this case, there is no reason to be concerned, as soon as the condition tends to be common and be related to stress , food and even the use of contraceptives.

Pink discharge after intercourse

After intercourse with penetration, pink discharge may occur. This is because, during penetration, small lesions can occur in the vaginal mucosa, leading to micro-bleeding.

It is important for the woman to observe how often this occurs and whether the intensity of the bleeding gets stronger and stronger (red). In such cases, it is important to seek gynecological guidance.

When it occurs punctually after intercourse, there is usually no cause for concern. But if it is constant, it can be a sign of poor lubrication or other problems.

It is worth remembering that pain, discomfort or injuries are never normal during sexual intercourse, and in such cases gynecological consultations are necessary.

Pink discharge taking contraceptives: what can it be?

The use of contraceptives can cause changes in the natural discharge. At the beginning of use, observing the presence of pink discharge may be more common, as it affects the hormonal rate.

In addition, it is common that until adaptation of the organism, small escape bleeds occur, so that the vaginal mucus mixes with the blood and turns pink. In addition, changing contraceptives or not using them correctly (forgetting doses) can be the source of the pink discharge.

Is pink discharge before or after menstruation normal?

It depends. Before menstruation, which ceases spontaneously and is not followed by the usual menstrual flow, it may be a sign of pregnancy, in the case of nidation.

However, it may also be just an escape from menstruation caused by hormonal changes. If pregnancy is suspected, it is important to have a pharmacy or blood test.

When discharge is observed after the end of menstruation, the reasons may be different. One of them is the possibility of being only remnants of blood from the cycle.

In these cases, vaginal discharge may be pink, but the most common is that it is closer to brown.

After menstruation, because the woman is far from the fertile period , pink bleeding is less likely to be a nest. But it is important that the woman who does not want to get pregnant takes other care besides being based on the table.

This is because hormonal changes can occur and the egg be released ahead of time, increasing the chances of a pregnancy.

Anyway, in the face of a pink discharge, it is important to be aware of other signs and see a doctor if you suspect a disease or pregnancy.

Pink discharge in pregnancy

The pink discharge is one of the first signs of a pregnancy. It is actually an escape that usually lasts 2 to 3 days, which indicates that the egg has been fertilized by a sperm, has reached the uterus and implantation is taking place in the uterine wall.

Therefore, it occurs up to 3 days after sexual intercourse, accompanied in some cases by the presence of colic.

These cramps are normal and pass, in most cases, without the need for drug treatment.

The pink color of the discharge is due to the presence of blood in the secretion, a common escape to happen at the time of nesting, right after the arrival of the fertilized egg in the uterus.

In addition to being a sign of pregnancy, pink discharge can also occur during a more advanced pregnancy, sometimes normal due to rupture of blood vessels while the placenta develops and invades the muscle layer of the uterus.

If in the first case it is a normal condition, in the latter it is necessary to have double care, as it can mean a miscarriage.

It is important to observe the pattern of duration and amount of bleeding, in order to distinguish normality or abortion. Generally, physiological bleeding occurs in a few days and is scarce daily (it does not even fill an absorbent).

During the first 3 months of pregnancy, the woman’s body shows a significant increase in blood flow. Normally, the amount of blood in the body is 4.5 liters.

In pregnancy, it can reach 6.7 liters. As a result, even physical exertion and sexual intercourse can result in the rupture of a small blood vessel, causing pink or brown tones in vaginal secretions.

In order to investigate whether the bleeding is a pregnancy and to confirm the pregnancy, it is important that the woman recognizes other symptoms of pregnancy and has a test.

With more advanced pregnancy, any bleeding must be assessed by the obstetrician.

How long can a vaginal discharge last?

If it is the case of a pink discharge caused by a pregnancy (nesting), the duration is approximately 2 to 3 days. This is a case that you can estimate the duration, but the duration depends on the cause.

The ideal is to seek medical help even before the pink discharge ceases, as it may be a more serious condition.

If in addition to the discharge there are other symptoms, such as colic, itching, strong odor or burning, the urgency for a diagnosis is even greater.
