Ay honestly sis, medyo mahirap humanap ng super cheap ultrasound na de-quality pa, pero try mo yung government health centers or barangay clinics muna, usually mas mura dyan kumpara sa private hospitals! A few of us dito sa Alabang area nag-go sa Ospital ng Paraaque or the smaller clinics near SM City Alabang, and okay naman ang service nila without breaking the bank, kaya siguro worth checking out din yan.
