Intrauterine devices (IUDs) can be a safe, effective, and relatively easy birth control option. However, pregnancy can occur if the IUD dislodges or is not placed properly. Dr Elysia Moschos, associate professor of obstetrics and gynecology, and Dr Diane M. Twickler, professor of radiology, at the University of Texas Southwestern Medical Center in Dallas, studied ultrasound findings, clinical symptoms, and outcomes for women with first-trimester pregnancies despite having intrauterine devices to better understand this issue.
