Hi mama! At 19 weeks, ang ultrasound tech usually na makikita na nila if girl or boy, pero depende talaga sa position ng baby at skill ng technician, sometimes kailangan pa ng follow-up scan pa lang makita clearly. Best bet is to ask your OB directly during your next checkup, or if gusto mo talaga alam, pwede ka mag-request ng detailed anatomy scan na specifically for gender confirmation lang.
