Pink discharge, in most cases, is considered to be normal and not a sign of concern. It may be associated with the menstrual cycle, use of birth control or hormonal changes.

However, in some cases, pink discharge can be a sign of other conditions that require assessment, especially if there are also other symptoms (like abdominal pain, nausea, or foul odor). Pink discharge in these cases may be associated with ovarian cysts or pelvic inflammatory disease.

Some conditions that can cause pink discharge include:

1. The beginning or end of the menstrual cycle 

Some women may have pink discharge at the beginning or at the end of their menstrual cycle. It is usually a combination of menstrual blood and normal vaginal discharge.

What to do: Having pink discharge at the beginning or at the end of menstruation is perfectly normal, therefore no treatment is necessary.

2. Hormonal imbalance

When a woman undergoes hormonal changes, she may have pink discharge. This happens when estrogen levels are not sufficient enough for keeping uterine lining stable, which causes it to shed. The shedding can mix with normal vaginal discharge, giving it a pink color.

What to do: Hormonal imbalance can be influenced by several factors, like stress, bad diet, being overweight, or a disease. Therefore, it is important to visit a general practitioner or endocrinologist in order to understand the cause of the imbalance.  

3. Use of contraceptives

Some women have pink discharge when they start or change contraceptives. This is more common when the contraceptives used have low estrogen doses, or if they have progesterone in them. 

Additionally, pink discharge can also happen if the contraceptive is not taken properly.

What to do: Generally, this symptom arises during in the first 3 months of starting the contraceptive. However, if you experience pink discharge for over 3 months, you should follow-up with your prescriber. 

4. Ovarian cysts 

An ovarian cyst is characterized by liquid-filled sac that can form inside or around the ovary. Many women can be asymptomatic, but others may experience symptoms such as pink discharge, pain, changes to cycle, or difficulty getting pregnant.

What to do: Ovarian cysts are only treated in certain situations (e.g. if they cause intense symptoms or are very large). The doctor may recommend the use of a contraceptive pill that contains estrogen or progesterone to control the cyst, or, in extreme cases, surgical removal of the ovary may be advised.

5. Pregnancy

Pink discharge can also be a symptom of early pregnancy. It is associated with implantation of the embryo to the endometrium (the lining of the uterus).

What to do: Pink discharge during implantation is perfectly normal, even though it does not happen to all women. However, if the intensity of the bleeding increases, see your doctor or obstetrician.

6. Pelvic inflammatory disease

Pelvic inflammatory disease is an infection that starts in the vagina and rises, affecting the uterus, the fallopian tubes and the ovaries. It can also spread to a great part of the pelvic area and even the abdomen, creating symptoms such as pink, yellowish or greenish colored discharge, bleeding during sexual intercourse, and pelvic pain.

What to do: Generally pelvic inflammatory disease is treated through antibiotics. However, depending on the severity of the illness, surgery may be necessary.

7. Miscarriage

Pink discharge can also be a sign of miscarriage, which is very common in the first 10 weeks of pregnancy. It can happen due to the fetus not developing properly, the mother consuming too much alcohol or medication, or abdominal trauma. 

Generally, the signs and symptoms occur suddenly and can include fever, strong abdominal pain, headache, and pink discharge that can evolve to greater blood loss with clots.

What to do: If you suspect you are having a miscarriage, go straight to the emergency department. 

8. Menopause

When a woman is in the transition period to menopause, she undergoes hormonal changes, which result in changes to the menstrual cycle. As a consequence, symptoms such as pink discharge, hot flashes, sleep disturbances, vaginal dryness, or mood changes can occur. 

What to do: A woman going through menopause should only undergo treatment if symptoms cause discomfort and compromise quality of life. In some cases, hormone replacement therapy or diet supplements may be advised.
