Bleeding During Pregnancy

Bleeding occurs in approximately 20 - 40 % of pregnancies. Vaginal bleeding can range from light spotting to severe bleeding and passage of clots. It is important to understand the nature of bleeding and contact your doctor if you have any bleeding during your pregnancy.

Light spotting at about 6 to 12 days after conception is normal. This occurs when the fertilised embryo implants into the wall of the uterus. Light spotting is common and most women continue to have a normal pregnancy. If the bleeding is severe like menstrual bleeding and associated with cramps it may be a sign of some serious underlying problem.

Some of the causes of bleeding are:

An infection in the vagina or cervix may cause bleeding.
Bleeding could be a sign of miscarriage. In that case there may be other associated symptoms such as:
  • abdominal cramping or back pain
  • passage of tissue along with bleeding
Molar Pregnancy
This is a disorder of fertilisation which causes growth of abnormal tissue in the uterus. It is associated with
  • Vaginal discharge of grape-like clusters
  • Severe nausea and vomiting
  • No fetal movement or heart rate detected
Ectopic pregnancy
This occurs because the fertilised ovum has implanted itself outside the uterus, usually in the fallopian tube. This condition is potentially life threatening for the mother and needs to be diagnosed and treated promptly.
Sexual intercourse
Sometimes bleeding can occur after sexual intercourse as the cervix is vascular during pregnancy.
Placenta praevia
Bleeding can occur when the placenta has implanted low in the uterus.
Placental Abruption
This is usually a problem that occurs in third trimester due to early separation of placenta from the uterine wall.
