Usually, bleeding occurs during the first trimester of pregnancy and this can’t be a sign of a problem. If the bleeding during pregnancy occurs in the second or third trimester, it can be a sign of possible complications.
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.
Miscarriage:
One of the most possible signs of bleeding during pregnancy is a miscarriage. But it doesn’t mean that women who notice bleeding will certainly have a 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 a 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 to 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 the third trimester of pregnancy can be a sign of labor. When you are a 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.
