Congrats sa pregnancy! The Congenital Anomaly Scan (usually around 18-20 weeks) can range from around 2,500 to 8,000+ pesos depending sa hospital or ultrasound clinic, private centers tend to charge more than public hospitals, and some OBs include it na sa package mo na, so best to ask your doctor kung included na o separate ang bayad. A few of us moms did ours sa government hospitals and it was way cheaper, pero sometimes may waiting time lang, pero totally worth it para sa peace of mind!
