Subchorionic hematomas, or subchorionic hemorrhages, are common ultrasound findings in early pregnancy. However, their significance is uncertain. Some believe they increase the risk of many pregnancy complications, including pregnancy loss / miscarriage. In this study of almost 3000 women, we found that Subchorionic hematoma does not increase the risk of pregnancy loss prior to 20 weeks. This information is reassuring as nearly 20% of women will have this finding on ultrasound.
