Hi mama! Most of my friends go either sa OB clinic nila mismo or sa imaging centers like Metro Scan and Ultrasound Plus, it really depends kung saan mas accessible sa inyo and kung ano na-recommend ng OB ninyo, kasi some doctors have preferred centers pa. Price-wise, it ranges from around 3,000 to 6,000+ pesos depending sa facility and if gusto ninyo ng 3D/4D imaging, so maganda mag-ask muna sa OB ninyo before booking para may idea na kayo ng exact cost!
