Threatened Abortion Threatened Miscarriage. Medically reviewed by Nicole Galan, RN. Pregnancy losses that occur between 13 and 19 weeks gestation are called second-trimester pregnancy losses or second-trimester miscarriages. A pregnancy loss at 20 weeks or greater gestation is not called a miscarriage, but a stillbirth—where the fetus dies in the mother's uterus.
According to the American College of Obstetricians and Gynecologists, approximately 80 percent of miscarriages happen within the first trimester. As pregnancy progresses, miscarriage risk decreases. In addition, your risk of miscarriage drops significantly after a doctor detects a heartbeat on an ultrasound. If you're wondering when miscarriages occur, you may also have questions about how common miscarriages are.
The good news is that by the time you actually get a positive pregnancy test, your risk of miscarriage will be at the lower end of that range. In an older study in the New England Journal of Medicine , researchers followed women over a combined total of menstrual cycles, with total pregnancies.
They found that 22 percent of the pregnancies ended before they could be detected clinically such as by standard urine pregnancy tests. Including the early miscarriages , the total miscarriage rate was 31 percent.
Current evidence backs up this older study, suggesting that anywhere between 8 and 20 percent of recognized pregnancies will end in miscarriage and 30 to 40 percent of all conceptions end in miscarriage. While early pregnancy loss occurs in about 10 percent of all recognized pregnancies, second-trimester miscarriages occur in about 1 to 5 percent of pregnancies.
Stillbirth occurs in about 0. About half of miscarriages are caused by chromosomal abnormalities, making these problems the single most common miscarriage cause. Most of these are random one-time occurrences that are not inherited from the parents. The earlier in pregnancy a miscarriage occurs, the more likely it was caused by a chromosomal abnormality.
The miscarriage rate after 15 weeks for fetuses that are free of chromosomal or structural abnormalities is only about 0.
Usually, these abnormalities are aneuploidies, meaning there is an incorrect number of chromosomes, either an extra chromosome as in the case of trisomy 21 or Down syndrome or a missing chromosome. The biggest miscarriage risk factor is a mother's age. According to the American College of Obstetrics and Gynecologists, the number of miscarriages in the first trimester for women increases dramatically as a woman ages. Here are the statistics showing this rise:.
The miscarriage rate is lower for women who have had a child previously, about 5 percent up to 20 gestational weeks. If you have experienced a miscarriage in the past, are worried you may have one, or both, please know that you are not alone. If your worry is persistent and affecting how you feel and function, be sure to seek guidance from your doctor.
