When you are diagnosed as having a miscarriage it is a devastating time and if you have not been through this before all of the jargon surrounding it can be quite confusing.
There are quite a few different types of miscarriage and the American Pregnancy Association has classified them as follows:
- Threatened miscarriage: Early pregnancy uterine bleeding accompanied by cramping or lower backache. The cervix remains closed. This bleeding is often the result of implantation.
- inevitable or Incomplete miscarriage: Abdominal or back pain accompanied by bleeding with an open cervix. Miscarriage is inevitable when there is a dilation or effacement of the cervix and/or there is rupture of the membranes. Bleeding and cramps may persist if the miscarriage is not complete.
- Complete miscarriage: Bleeding and cramping is strong but subsides quickly once the embryo has left the body.
- Missed miscarriage: When a woman has a miscarriage and doesn’t know it. There are usually no outward signs as the embryo is not expelled from the body.
- Blighted ovum: A fertilized egg implants into the uterine wall, but fetal development never begins. Often there is a gestational sac with or without a yolk sac, but there is an absence of fetal growth.
- Ectopic pregnancy: This occurs when the embryo implants somewhere other than the uterus. If the body does not cause a miscarriage, a doctor may be forced to terminate the pregnancy.
- Molar pregnancy: The result of a genetic error during the fertilization process that leads to growth of abnormal tissue within the uterus.
