Hi mama! Congrats on your pregnancy! Honestly, best way pa rin to find a good OBgyne sa La Paz is to ask your local health center or midwife for referrals, they usually know the reliable doctors around the area. A few of my mum friends from nearby provinces say word-of-mouth from other moms sa your barangay is super helpful din, kaya maybe ask around sa mommy groups or neighbors na na-deliver na locally, they can tell you kung sino ang approachable at attentive talaga. Since first time ka, importante talaga na comfortable ka sa doctor mo, so take your time asking around!
