Decidual Bleeding

What is Decidual bleeding?

It is a medical condition characterized by shedding of some parts of the lining of the uterus on the first trimester of pregnancy. In layman’ term, it is called the first trimester bleeding. It occurs from a particular part of the decidua that is not yet covered by the developing placenta and embryo.

Statistics showed that about 30% of women are experiencing decidual bleeding. The bleeding is somewhat similar to that of the regular menstrual bleeding and so many women mistaken it for a monthly period when in fact they are already pregnant. (1, 2, 3)

How to recognize a decidual bleeding?

A pinkish to brownish vaginal discharge on the first few months of pregnancy is one of the signs of decidual bleeding. It looks exactly the same as the menstrual bleeding. However, if you have had sexual contact, then you might want to begin to suspect that you are pregnant.

You can perform a pregnancy test. If you are suspecting that there is an underlying medical condition other than pregnancy, then you need to consult your doctor. (3, 4, 5)

Is decidual bleeding harmful?

A decidual bleeding typically occurs during pregnancy specifically on the first few months of pregnancy. It is because of the excessive hormone imbalance leading to rupture of some parts of the uterine lining. Bleeding in any parts of the uterus is dangerous during pregnancy but in the case of decidual bleeding, it does not cause any harm to the mother and the fetus.

However, if you are experiencing symptoms other than mild bleeding such as lightheadedness, weakness, and abdominal pain, then you need to consult your doctor right away. This is to eliminate the chances of miscarriage and other complications that may come along. (4, 5, 6)

What causes decidual bleeding?

The main cause of decidual bleeding. If you are about to have a menstrual flow or you are pregnant, your body undergoes changes which also affects your hormone level. Hormonal imbalance is common leading to shedding off of the uterine lining leading to a decidual bleeding. Every time the uterine lining is shed off, bleeding takes place.

If you had a sexual contact and you notice some sort of spotting along with other presumptive pregnancy symptoms such as dizziness, nausea, and vomiting, and breast tenderness, then you need to conduct a pregnancy test or better yet consult your obstetrician/ gynecologist.

If you are pregnant and you are experiencing any signs of bleeding, then the more you need to consult your doctor as it could be a risk to complication to your pregnancy. (4, 5, 6)

Treatment for decidual bleeding

If you are having a spotting for an unknown reason, then you need to seek medical help. See an OB/GYN and have yourself submitted for physical examination and other diagnostic procedures when deemed necessary. If it is indeed a decidual bleeding, then no specific treatment is required. A decidual bleeding does not possess any harm both to the mother and the baby.

However, if the bleeding gets heavy and the patient complains of other alarming symptoms such as pain, discomfort, and fever, then you need to seek immediate medical attention. A decidual bleeding should not last for longer than a day. It should not be a heavy flow.

Profuse bleeding or bleeding for more than a day could be linked with impending miscarriage, ectopic pregnancy, molar pregnancy, vaginal infection, cervical infection, and even cervical cancer. (6, 7, 8)

Facts to keep in mind:

  • A decidual bleeding is a mild bleeding that looks like a spotting. Women mistook it for a regular menstrual flow when in fact they are already pregnant. In the case of decidual bleeding, the lining is not fully attached to the placenta and so a tiny part of the lining is expelled by the body causing bleeding.
  • Decidual bleeding is short-lived, meaning, it will not last longer than a day.
  • Decidual bleeding usually occurs on the normal days of the menstrual cycle.
  • A decidual bleeding should not be a cause for concern. However, any forms of spots that occur during pregnancy should not be taken for granted as it could be a sign of an early miscarriage or ectopic pregnancy. It is important to seek professional help if you feel something is not right in your body.
  • The color of decidual bleed ranges from red, dark red, to brown in color. Some women notice pink blood caused by a mixture of body fluid in the blood.
  • A decidual bleeding is usually not a cause for concern as the bleeding subsides after a day or so. When it is a decidual bleeding, the mother and the fetus will not be in danger.

A decidual bleeding is nothing but a mild spotting caused by hormonal imbalance as the women’s body go through many changes during pregnancy. If you feel like you could be pregnant and you notice a spot of blood on your underwear, then might as well conduct a pregnancy test or better yet consult your doctor.

There is a fine line between decidual bleeding and bleeding due to miscarriage and/or ectopic pregnancy. For your safety as well as the welfare of your baby, you need to consult your doctor. (5, 8, 9, 10)
