Ay congratulations sa baby, mama! Honestly, 70% is pretty confident na but hindi 100% sure talaga, maraming cases na kami ng friends na akala boy pero girl pala, especially if the tech had a limited angle or if baby was positioned awkwardly that day. Mas nagiging accurate usually around 32 weeks onwards kaya you can always ask for another scan if you want to be really sure bago bumili ng daming blue stuff!
