We have spoken to Dr. Rijafin R, Senior Consultant, Obstetricians and Gynaecologists, Cloudnine Group of Hospitals, Old Mahabalipuram Road, Chennai to answer all your questions.

Bleeding during the first trimester

Any pregnancy is divided into three trimesters and the causes and treatment of problems are different in each trimester. The chances of bleeding in the first three months or 12 weeks of pregnancy are between 15% and 20%. This means that two out of 10 pregnant women may experience bleeding in the first trimester. In such a situation, the probability of miscarriage is 10% to 15%.

If bleeding occurs in the first 14 days, the miscarriage rate remains between 45% and 55%. Stomach cramps with heavy bleeding can lead to miscarriage in the beginning.

Bleeding during second and third trimesters

In the second and third trimesters, the woman may experience bleeding due to problems in the cervical. In such a situation, the water bag bursts and after this blood comes.

Vasa Previa

Vasa previa is such a dangerous condition, in which blood vessels cross the opening of the birth canal. This can be dangerous for the child. You should go to the doctor immediately. In such a situation, the baby can be deprived of oxygen, which can lead to bleeding.

Placenta previa

This is a condition in which the placenta comes to the lower part of the uterus. It partially or completely covers the birth canal. In such cases, the pregnant woman may bleed without any pain. For this, you should go to the doctor immediately.

Abrupsio Placenta

In about 1% of pregnancies, the placenta separates before labor pain begins. This can lead to heavy bleeding, which can be dangerous for both mother and baby.


Bleeding at the end of pregnancy can be a sign of labor. This is a sign that your baby is ready to come into this world.

Molar Pregnancy

However, molar pregnancy is very rare. But, it happens when the tissue develops inside the uterus instead of the baby. In such cases, the woman experiences symptoms similar to pregnancy, including vomiting, severe nausea and rapid growth of the uterus. In such cases, the only way to keep the patient healthy is to remove the tissue.

Ectopic pregnancy

Ectopic pregnancy occurs when the fetus begins to develop outside the uterus (mostly in the fallopian tube). The probability is about 2%. In such cases, the woman may experience mild headaches, syncopeal attacks and severe abdominal cramps.

Other reasons

Sometimes, the woman may experience bleeding during implantation. It can last for about 10-14 days. Other causes of bleeding during pregnancy include polyps in the cervix, cervix or vaginal infection, cancer, polyps and cervical changes during the gestation period.

Some causes are harmless, while others can be dangerous to your life. In any case, bleeding during pregnancy should not be ignored. It is best to go to a gynecologist immediately if needed to overcome any problem.
