Ay mama, hindi talaga 100% sure kahit anong gender reveal test kaya laging may slight chance na surprise pa rin! Even ultrasound and blood tests like NIPT ay very accurate na but there's always that tiny percentage ng error, so some babies really do surprise their parents on delivery day hehe. A few of my mum friends thought babae based sa ultrasound pero boy talaga came out, so mas okay lang mag-expect ng both possibilities para hindi disappointed, you know? At the end of the day baby is baby naman!
