Other research puts the percentage at around 10–15%. Will I experience a pregnancy loss?Ī 2012 study looked at the overall chance of pregnancy loss during the first and second trimesters and found it to be between 11–22% in weeks 5 through 20. Stillbirth is relatively rare and is getting rarer because very young babies may be able to survive outside the womb thanks to modern technology.Īccording to a research group based in the United Kingdom, there is a minimal chance that a baby born at 22 weeks will survive. Weeks 14–20īetween weeks 14 and 20, the chance of experiencing a miscarriage is less than 1%.īy week 20, a pregnancy loss is known as a stillbirth, and this may cause a person to go into labor.
In the second half of the first trimester, the rate of miscarriage seems to be 2–4%. In most cases, it is possible to detect a heartbeat on an ultrasound around week 6. The same study suggested that after week 6, the rate of loss drops to 5%. One 2013 study found that the overall chance of losing a pregnancy after week 5 is 21.3%. The rate of miscarriage at this point varies significantly. Most people will never know that they were pregnant, though some may suspect that they were because of pregnancy loss symptoms. By week 4, they may be able to get a positive result on a home pregnancy test.Īs many as 50–75% of pregnancies end before getting a positive result on a pregnancy test. Implantation usually occurs around 3 weeks after a person’s last period and about a week after ovulation. Also, people may change any potentially damaging lifestyle habits they have once they know that they are pregnant.Ī general estimate of miscarriage risk by week is as follows. This is why most miscarriages occur early in pregnancy.Īs the fetus gets stronger, it may be less vulnerable to harm. Even if a person has this type of pregnancy loss, they can generally go on to have a healthy pregnancy in the future.įetuses are most vulnerable early in development, so other factors - such as exposure to alcohol - can have the most damaging effects at this time. Early in pregnancy, genetic issues are a major cause of miscarriage.Īround 80% of pregnancy losses occur during the first trimester, between 0 and 13 weeks.Īlthough the loss is often devastating, these genetic issues mean the baby could not have survived outside the womb. Most pregnancy losses are due to factors that the person cannot control. Share on Pinterest Catherine McQueen/Getty Images
