Hi mama! A few of us did 3D/4D ultrasounds around that time, and honestly it's such a sweet experience to see baby's face na! I'd check with your OB kung available sila or if they can refer you to a clinic that does it, most diagnostic centers offer it, though some prefer to wait till 6-7 months when baby's features are clearer, pero 5 months is doable pa rin naman.
