A 25-year-old woman whose menses are 2 weeks late, presents to her physician for evaluation. She also complains of fatigue, morning nausea, and mood changes. She is a nulliparous with previously normal menstrual cycles and no known medical conditions. She had an intrauterine device (IUD) placed 6 months ago. The patient’s vital signs are as follows: blood pressure 120/80 mm Hg, heart rate 72/min, respiratory rate 12/min, and temperature 36.5℃ (97.7℉). The physical examination is unremarkable. The gynecologic exam revealed cervical cyanosis and softening, uterine enlargement, and non-palpable adnexa. A transvaginal ultrasound examination is performed to check the IUD position. Ultrasonography revealed 2 uterine cavities; one cavity had a gestational sac and the intrauterine device was in the other uterine cavity. The cavities are fully separated but there is one cervix. What is the most likely etiology of this patient’s condition?
