Need ba tlga ung CAS?or pwde nman khit ung pelvic ultrasound lng? Currently 24weeks.

My OB told me, that if I was sure na walang family history ng birth defects, down sydromes, at intake ng high risk medicines during pregnancy.. You may do pelvic ultrasound. But if you have budget and unease and want to ensure every details of your baby, highly suggest to do CAS
