Routine 2D transvaginal US 23 days following transfer was suspicious of monochorionic twin or triplet pregnancy; therefore, a 3D US was performed on the same day demonstrating clearly a single gestational sac with three yolk sacs and three foetal poles (CRL of 4.5, 3.1 and 3.0 mm) (Fig. 2a). On day 36 following transfer, 3D US confirmed a MCTA pregnancy (Fig. 2b).
