Hi mama! I don't have the specific schedule details for QC General Hospital's prenatal clinic, pero I'd suggest calling their OB department directly or going in person sa hospital to ask, usually merong walk-in slots, but better to confirm nalang para hindi ma-hassle, lalo na kung matagal ka nang naghihintay. A few of my mum friends went there and sabi nila okay ang service, kaya definitely worth reaching out to them!
