to everyone ?

may mga nagpapaultrasound to check the gender as early as 16/17 weeks pero pinakaadvisable ay 20 weeks onwards. sa umpisa kasi ng development ng reproductive organs ng babies, parehas ang itsura kaya minsan napagkakamalan na girl pero boy pala, di pa kasi nagdedevelop to the point na may identifying feature na kaya maaga pa if less than 20weeks.
