Ah sis, depende talaga sa clinic or hospital na pipilihan mo! Sa mga private hospitals dito, ang TVS (transvaginal ultrasound) usually around 1,500 to 3,500 pesos, pero sa government hospitals or lying-in clinics mas mura, sometimes 500 to 1,000 lang. Best thing is to call ahead sa OB mo or sa clinic mismo para sure ang exact price, kasi may iba pang charges pa din sometimes depending sa packages nila. A few of us preggy moms usually ask din kung pwedeng i-bundle with the full ultrasound package para mas sulit!
