First Trimester Bleeding: Causes of Bleeding in First Trimester
About 20% of women have some form of bleeding during the first 13 weeks of pregnancy and some possible causes are; implantation bleeding, ectopic pregnancy, miscarriages, infection and cervical changes.
Implantation Bleeding: This is otherwise called spotting. Please note that implantation bleeding is normal. It occurs when the fertilized ovum or egg gets implanted into the wall of womb or uterus. In many women, this is the first symptom of pregnancy they notice and maybe mistaken for normal menstrual bleeding. It occurs within the first 6 days to about 12days after you conceive. It is very light and may last for a few hours to days.
Miscarriage: Miscarriage is another common cause of bleeding in pregnancy. There are different forms or types of miscarriage but in all but one form, all the babies are lost. Types of miscarriage includes – threatened miscarriage, incomplete miscarriage, complete miscarriage and missed abortion.
It is important to note that it is only in threatened miscarriage which has been briefly explained below that the baby is alive. In other types of miscarriage, the babies are lost.
Threatened Miscarriage: It is also called threatened abortion. You have vaginal bleeding and abdominal cramps or pain but the cervix is closed and ultrasound shows that your baby is still alive.
Ectopic pregancy: An ectopic pregnancy is any pregnancy in which the fertilized egg or embryo is implanted outside the uterus. It occurs only in about 2% of pregnancies and can be life-threatening. Commonest site of ectopic pregnancy is the fallopian tubes which may rupture and cause severe bleeding into the abdomen.
Apart from bleeding, other symptoms of ectopic pregnancy includes lower abdominal pain or severe camps. There maybe light headedness of even fainting attack.
Molar Pregnancy: Also called Gestational Trophoblastic diseases GTD as it is a spectrum of different diseases. It is an abnormal form of pregnancy in which abnormal tissues are formed in the uterus. Molar pregnancy is characterized by passage of vesicles or bubble-like substances from the vagina as well as exaggerated symptoms of pregnancy such as nausea and vomiting with rapid enlargement of the uterus as well.
This is particularly dangerous as some of the disease that make up molar pregnancy are cancers. So it is very important to take note of this.
