Hey mama! I'm not from Lipa City kaya hindi ako makakatulong dito, pero I'd suggest posting this sa Lipa City moms group or asking directly sa Ospital ng Lipa mismo, they'd know best kung may free ultrasound programs sila or kung may payment plans available. A few of my mum friends from other areas say hospitals usually have info about government programs or promos, so worth a call talaga!
