Hey mama! From what a few of us have shared sa group, CAS ranges from around 1,500 to 3,500 pesos depending sa hospital or clinic, private hospitals tend to be pricier, pero some government centers offer it cheaper or covered na ng benefits if may company insurance ka. Best to call ahead and ask directly sa OB mo or sa ultrasound center kasi talaga may variation, at sometimes may package deals if combined na with other prenatal scans!
