When to know baby's gender

Mas better na siguro 25-32 weeks. Upon checking on my baby’s gender when I’m at my 23 weeks naka breech kasi sya pero na-detect na it’s a baby girl then nagpa-ultrasound ako on my 32nd weeks surprisingly it’s a baby boy. Ayun nga almost complete na gamit ni baby pink colors mostly yung mga nabili. 😂 luckily nagpa-ultrasound ulit ako kung hindi baka masuprise kami na boy si baby pag labas 😂
