Ay, honestly sis, di ko sure ang specific clinics sa Dasma/GMA area, pero a few of us moms usually go to the bigger malls like SM Dasma or even SM Bios Cavite kasi may ultrasound centers doon na mas affordable, ask around sa their OB clinics or check if may third-party imaging centers na nakaka-quote better rates! Try mo ring mag-inquire directly sa nearby hospitals like Perpetual Help o Medical City Cavite, usually they have packages din for 3D/4D ultrasounds na mas reasonable ang presyo compared sa private centers.
