Causes of Abnormal Vaginal Bleeding in Pregnancy

Possible causes of first semester bleeding are:

Implantation

Implantation normally occurs around 6-12 days after conception. But most common 6-7 days after conception.

When a sperm meets a matured egg that has been released during ovulation. Conception occurs. Then the fertilised egg travels down the fallopian tube while dividing rapidly.

It finally arrives in the uterus around 6-7 days post conception. Although ​it could take longer up to 12 days in some women.

The uterine lining provides a great place for the embryo and as well as nourishes it.

The embryo then digs deep into the lining in the walls of the uterus to implant itself.​

This implantation process may cause some blood to flow and as well as cramping.

Ectopic Pregnancy

Ectopic pregnancy occurs when a fertilised egg implants itself outside the uterus. Especially in the fallopian tube.

The proper place for an embryo ​to implant itself is in the uterus.

An ectopic pregnancy is severe and can be threatening to the pregnant woman. Because if the embryo keeps growing in the fallopian tube, it can burst and this a very dangerous situation to be in.

Only 2% of pregnancies end up being ectopic. Other symptoms to look out for are: abdominal cramping and feeling light headed.

Miscarriage

Miscarriage is one of the most common causes of bleeding while pregnant. A miscarriage is the loss of a baby before the 20th week.

Not all women who experience abnormal vaginal bleeding end up in miscarriage.​

Placenta Abruption

Placenta abruption occurs when the placenta detaches itself from the walls of the uterus. It is the separation of the placenta from the lining of the uterus.

It usually occurs in the third trimester and it happens in only 1% of pregnancies.

It is a life threatening condition for the mother and baby​. symptoms are: Vaginal bleeding, uterine tenderness, Abdominal pain, rapid contractions and abnormal fetal heart rates.

Preterm Labour

This occurs when labour begins sooner than expected. A normal pregnancy is expected to last for 40 weeks.

Any labour before the 37th week is termed premature.

If you notice up to five uterine contractions in an hour or less, call for the doctor or midwife immediately.​

Other symptoms are: menstrual-like cramps in the lower abdomen, excessive or abnormal vaginal discharge or blood.

Sexual Intercourse

Cramps and bleeding after intercourse may be due to the position of the cervix, or your man hitting the cervix during sex.

Other comfortable intercourse positions are recommended for pregnant women.​

Subchorionic Hemorrhage

Also known as subchorionic bleeding, it is the accumulation of blood between the uterus and the placenta.
