CAS is a special ultrasound made para icheck ng maigi ang body parts ni baby, tumatagal to ng almost an hour or more. Pelvic ultrasound is just a normal ultrasound lang. Once they see the baby's length, your amniotic fluid, the gender, the heartbeat, ok na. Mas detailed si CAS kasi ultimo daliri ni baby or distance ng mga mata nya chinecheck. :)
