Know The 7 Major Causes of Bleeding During Pregnancy

Bleeding During Pregnancy

There are several reasons behind bleeding during pregnancy, such as:

Implantation bleeding:

Some women may experience little bleeding when the fertilized egg is implanted into the uterus.


One of the most possible signs of bleeding during pregnancy is miscarriage. But it doesn’t mean that women who notice bleeding will certainly have miscarriage. About 15-20% of pregnancies result in miscarriage.

Ectopic pregnancy:

During this condition, the fetus is implanted outside the uterus. It occurs 1 in 60 pregnancies and is less common than miscarriage.

Molar pregnancy:

It is a rare cause of bleeding during pregnancy. It causes the growth of abnormal tissue inside of the embryo. This condition is also referred as Gestation Trophoblastic Disease.

Placental abruption:

Bleeding occurs when the placenta is detached from the uterine wall before or during the labor. About 1% of the women may experience this kind of problem.

Placenta previa:

It happens when the placenta lies low in the uterus partly or completely covering the cervix. 1 out of 200 pregnancies may experience this condition.

Preterm labor:

Vaginal bleeding during third trimester of pregnancy can be a sign of labor. When you are few weeks due, the mucus plug may pass, which contains mucus and blood. In case you notice the condition little early, you might have preterm labor and should immediately consult your doctor.
