Is bleeding a normal part of pregnancy?

Bleeding is common in pregnancy. Around 15% to 25% of the time, it is more prevalent during the first trimester of pregnancy. Most women who experienced early bleeding go on to have a healthy and successful pregnancy.

However, bleeding can also happen in the latter weeks of pregnancy, where it can be more serious and alarming than in the early weeks.

Implantation bleeding or spotting commonly occurs during the first two weeks after you conceive. This happens due to the implantation of the fertilized egg in the lining of the uterus.

Spotting consists of droplets of blood that only becomes noticeable after you wipe your vagina with a tissue or if you notice a brownish, pinkish stain on your underwear.

Remember that spotting is different from bleeding. Spotting refers to small amounts of blood or droplets, while bleeding is a heavy flow of blood that can completely soak a menstrual pad.

Make sure to give your doctor a heads up if you experience any type of bleeding during pregnancy.

What causes heavy bleeding during pregnancy?

First trimester

The common causes of bleeding during the first trimester are:

  • Ectopic pregnancy. This occurs when the fertilized egg develops outside the uterus.
  • Miscarriage. Loss of pregnancy or death of the fetus before the 20th-week gestation.
  • Molar pregnancy. A pregnancy where an abnormally fertilized egg develops into a tissue instead of a fetus.
  • Threatened miscarriage. An occurrence of vaginal bleeding that indicates a woman’s risk of future miscarriage.
  • Subchorionic hematoma. The collection of blood between the uterine wall and the chorionic membrane or under the placenta.

Second and third trimester

Vaginal bleeding on the second and third trimester is due to:

  • Miscarriage or fetal demise
  • Incompetent cervix. A weakness of the cervical tissue that may lead to preterm birth or loss of pregnancy.
  • Placental abruption. This occurs when the placenta separates from the uterine wall resulting in heavy vaginal bleeding.
  • Placenta previa. A pregnancy complication where the placenta grows in the uterus and may cause bleeding throughout the pregnancy and delivery.
  • Placenta accreta. This is a serious pregnancy complication that takes place when the placenta or a part of the placenta secures itself tightly in the uterine wall. A pregnant woman who’s been diagnosed with this condition is at risk of having a life-threatening blood loss during delivery.
  • Preterm labor. A signal that the body is getting ready for labor. It usually happens after the 20th week and before the 37th week of pregnancy.

Postpartum Hemorrhage: Causes and Risk Factors

Blood clot during pregnancy

Pregnant women are more likely to develop blood clots during pregnancy and delivery. Blood clot formation during pregnancy is a natural bodily response to prevent loss of blood during birth.

However, blood clots can be dangerous, especially if they moves down the lower part of the body, which might lead to a condition known as deep-vein thrombosis (DVT).

To prevent this from happening, doctors may give the mother some medication that can help break down the clot and restore the normal circulation of blood.

When to see or call your doctor

Now that you know how much bleeding during pregnancy is normal, it will be easier for you to detect the signs if you need to call your doctor.

Give your doctor a call if:

  • You notice light bleeding or spotting for the first time.
  • You experience vaginal bleeding for more than 24 hours.
  • Bleeding becomes moderate to heavy that comes with clumps of blood and tissue.
  • Vaginal bleeding accompanied by abdominal pain, cramping, or fever.

Vaginal bleeding in the last few weeks of the third trimester might be an indication that you are going into labor.

Make sure to contact your doctor right away to confirm whether you’re about to give birth or if it’s a sign of a pregnancy complication.

Key takeaways

For expecting mothers, bleeding during pregnancy can be terrifying. Although it’s fairly common in about 20% of women, it is still the best option to inform your doctor about it.

Always remember that spotting is different from bleeding. If you’ve been having moderate to heavy bleeding, call for an emergency so you can get all the required tests immediately.

Also, remember to inform your partner and family members about the possible bleeding during pregnancy, so they’ll know what to do in case it happens.
