Miscarriages are also known as spontaneous abortion, or we can refer to them as the unexpected ending of a pregnancy. It is also considered pregnancy loss in medical terms. It is a phenomenon that comprises the death of an embryo before it is being delivered. Most miscarriages occur before a woman misses a menstrual period that is before they know or are aware that they are pregnant. These cases are about one-third to half of all pregnancies in the world. In some cases, people know that they are pregnant but result in miscarriage. This data is about 10 to 20% of the world.
Risk of Miscarriages
A miscarriage mostly in about 99% of cases occurs within the first three months of pregnancy. Only one percent of cases occur after 3 months or 20 week gestation period.
The miscarriages that occur after the three months of pregnancy are termed late miscarriages. But the time of miscarriage where is from person to person.
- A pregnancy loss or miscarriage can occur before a person is aware that she is pregnant. But if a healthy Heartbeat of the embryo is detected in ultrasound the chance of miscarriage is very low (approximately 10-15%).
- A woman less than 30 years of age has a 12 to 15% chance of pregnancy loss.
- A woman more than 35 years of age has a higher risk of miscarriage as compared to younger women. After the age of 35, the chance of miscarriage is about 20% and after the age of 40 the risk is about 40% and the risk is about 80% when a woman is more than 45 years old.
- Women who have more than two consecutive miscarriages are prone to a higher risk of pregnancy loss even at a younger age.
