Hi! Sorry, wala akong specific recommendation sa area ninyo, pero a few of us moms here usually go to the bigger diagnostic centers sa Antipolo proper or Taytay town proper, mas maraming options doon usually, at kaya magcompare ng prices. I'd suggest calling ahead sa hospitals or diagnostic clinics near your area kasi ang CAS ultrasound pricing varies, pero kung may friends kayo sa nearby villages, tanungin ninyo kung saan nila ginawa at magkano, usually mas may idea ang local parents dyan!
