All patients with intrauterine pregnancy on initial obstetric ultrasound presenting to an infertility clinic between January 2015 and March 2018 (\n n\u00a0=<\/jats:italic>\n \u00a01210), regardless of treatment cycle, were included.

There was no association between subchorionic hematoma and first trimester miscarriage; however, among patients with subchorionic hematoma, those who reported both bleeding and cramping had an increased probability of miscarriage compared to those without symptoms (0.62 vs. 0.12,\n P\u00a0<<\/jats:italic>\n 0.001).
