Usually from 5 to 6 months pwede na. Try niyo po sa www.facebook.com/OLGUltrasoundCenter magaling sila dun at malinaw ang ultrasound.
Yung sa amin is 4months po and identified naman correctly ang gender ni baby. Pero if gusto mong sure talaga, wait mo na mag-6 or 7months
6 months or 7 months pra sure.
