Early 1st trimester pregnancies can be challenging to risk stratify when patient present with bleeding or pain. The pregnancy may be still too early for transabdominal ultrasonography, which was covered in last week’s PV card. The same authors, Drs. Matt Lipton, Mike Mallon, and Mike Stone provide a great bedside clinical reference tool on performing the focused transvaginal ultrasound in pregnancy.
