Hey mama! From what I know, NT scan usually ranges from around 2,000 to 5,000 pesos depending on the clinic and kung gaano ka-detailed ang ultrasound, mga fancy hospitals with 3D/4D machines tend to charge more, pero ang basic NT scan mismo ay on the lower end. A few of my mum friends did theirs sa OB clinics and reproductive centers, and they said to call ahead kasi may promo sometimes or package deals, especially if you're planning to do other prenatal tests din, worth asking! Congrats on your pregnancy, by the way!
