Ay mama, congrats sa 21 weeks! Sa Taguig area, maraming good options, Asian Hospital at Makati Medical are both super accessible from Taguig, and ang OB teams nila ay solid talaga, though medyo mahal. If gusto mo closer and mas affordable, St. Luke's Global City or even Ospital ng Makati ay decent din, and maraming friends ko nag-deliver na successfully doon. Best tip ko is to personally tour the maternity wards and ask which hospitals your trusted OB actually admits to, kasi yan talaga ang magiging basehan mo in the end!
