I heard somewhere that there was a 20% chance of a miscarriage, and 50% of those were due to a blighted ovum...The following is what the
American Pregnancy Association says:
For women in childbearing years, the chances of having a miscarriage can range from 10-25%, and in most healthy women the average is about a 15-20% chance.
An increase in maternal age affects the chances of miscarriage
Women under the age of 35 yrs old have about a 15% chance of miscarriage
Women who are 35-45 yrs old have a 20-35% chance of miscarriage
Women over the age of 45 can have up to a 50% chance of miscarriage
A woman who has had a previous miscarriage has a 25% chance of having another (only a slightly elevated risk than for someone who has not had a previous miscarriage)
What are the Warning signs of Miscarriage:
If you experience any or all of these symptoms, it is important to contact your doctor or a medical facility to evaluate if you could be having a miscarriage:
Mild to severe back pain (often worse than normal menstrual cramps)
Weight loss
White-pink mucus
True contractions (very painful happening every 5-20 minutes)
Brown or bright red bleeding with or without cramps (20-30% of all pregnancies can experience some bleeding in early pregnancy, with about 50% of those resulting in normal pregnancies)
Tissue with clot like material passing from the vagina
Sudden decrease in signs of pregnancy
The different types of Miscarriage:
Miscarriage is often a process and not a single event. There are many different stages or types of miscarriage. There is also a lot of information to learn about healthy fetal development so that you might get a better idea of what is going on with your pregnancy. Understanding early fetal development and first trimester development can help you to know what things your health care provider is looking for when there is a possible miscarriage occurring.
Most of the time all types of miscarriage are just called miscarriage, but you may hear your health care provider refer to other terms or names of miscarriage such as:
Threatened Miscarriage: Some degree of 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: A completed miscarriage is when the embryo or products of conception have emptied out of the uterus. Bleeding should subside quickly, as should any pain or cramping. A completed miscarriage can be confirmed by an ultrasound or by having a surgical curettage performed.
Missed Miscarriage: Women can experience a miscarriage without knowing it. A missed miscarriage is when embryonic death has occurred but there is not any expulsion of the uterus. It is not known why this occurs. Signs of this would be a loss of pregnancy symptoms and the absence of fetal heart tones found on an ultrasound.
Recurrent Miscarriage (RM): Defined as 3 or more consecutive first trimester miscarriages. This can affect 1% of couples trying to conceive.
Blighted Ovum: Also called an anembryonic pregnancy. 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: A fertilized egg implants itself in places other than the uterus, most commonly the fallopian tube. Treatment is needed immediately to stop the development of the implanted egg. If not treated rapidly, this could end in serious maternal complications.
Molar Pregnancy: The result of a genetic error during the fertilization process that leads to growth of abnormal tissue within the uterus. Molar pregnancies rarely involve a developing embryo, but often entail the most common symptoms of pregnancy including a missed period, positive pregnancy test and severe nausea.
