- Bleeding caused due to implantation:
Some women would experience normal spotting within the first six to 12 days after the fertilized egg implants itself in the lining of the uterus. The bleeding is very light and lasts from a few hours to a few days, and is often mistaken as light period.
- Miscarriage:The first few months after conceiving are the most crucial ones. Chances of miscarriage during this time are at its peak, and this often leads to bleeding in pregnant women. It also causes other symptoms like strong cramps in the lower abdomen area.
- Ectopic pregnancy:
In such a pregnancy, the fertilized embryo gets implanted outside the uterus, usually in the fallopian tube. If the embryo keeps growing, it can cause the fallopian tube to burst, causing bleeding, and can even prove to be fatal for the mother.
- Molar pregnancy:A rare condition in which abnormal tissues grow inside the uterus instead of the baby. In rare cases, the tissue can turn out to be cancerous and spread to other parts of the body.
Apart from the first trimester bleeding, there can be some complications during pregnancy that can cause bleeding in the later trimesters too.
Some of the causes are:
- Placenta previa:
Occurs when the placenta sits low in the uterus and partially or completely covers the opening of the birth canal. Can lead to bleeding and requires medical attention.
- Placental abruption:
In some rare cases, the placenta detaches itself from the wall of the uterus before or during labour and blood pools in between the placenta and uterus. Can be a threat to the mother’s health if not treated well.
- Uterine rupture:
In rare cases, scars from a previous C-section can tear open during pregnancy. Uterine rupture can be life-threatening, cause a lot of bleeding, and requires an emergency C-section.
- Premature labour:
Vaginal bleeding in late pregnancy would be a sign that the mother’s body is ready to deliver. A few days or weeks before labour, the mucous plug that covers the opening of the uterus will pass out of the vagina, and it will usually have small amounts of blood in it.
In the first trimester, bleeding is often seen to be a normal occurrence, but a doctor must be contacted if there is severe pain or intense cramps low in the abdomen, severe bleeding (whether or not there is pain), discharge from the vagina that contains tissue, dizziness and fainting, or the mother is running a fever of more than 100.4 or more degrees Fahrenheit.
Also make sure that mothers track their vaginal bleeding. Wearing a pad would help keep track of the quantity of bleeding, and record the type and colour of blood (for example, pink, brown, or red; smooth or full of clots).
Also, take any tissue that passes through the vagina to the doctor for testing, to aid diagnosis. Also, pregnant women should not use a tampon or have sex while they are still bleeding.
