Transabdominal and transvaginal ultrasound scans have been performed. The uterus is anteverted.
A live intrauterine pregnancy is identified. The gestational sac has an unusual morphology (tear drop) and appears to infiltrate into the anterior-inferior myometrium where there is evidence of a Caesarean scar.
The gestational sac also overlies the internal cervical os. An area of fluid superior to the gestational sac likely represents fluid within the uterine cavity at the level of the fundus.
Fetal heart rate is measured at 166 bpm. Gestational sac diameter and crown-rump length give estimated gestational age of 7 weeks + 5 days.
