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 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%.
