Sis, please schedule an appointment with a different OB as soon as possible, at 29 weeks, you really need consistent prenatal care, vaccines, and proper monitoring, at hindi normal na walang OGT at explanations pa.
I know it's stressful mag-switch ngayon, but a few of us moms in QC learned the hard way na if your OB isn't responsive or explaining things, it's time to move on, your peace of mind during pregnancy matters talaga. For partner hospitals, try Makati Medical, St. Luke's BGC, or Medical City Eastwood, they all have good OBs, though rates vary depending sa doctor. Best to call their OB department directly para sa recommendations based sa your budget, kasi ang fees ay iba-iba talaga.
Sorry na walang specific names agad, pero ask your friends din kung sinu ang OB nila na approachable, word of mouth talaga ang best way para mahanap. You deserve better care, mama.
