Ang normal talaga ay super different from mom to mom, kaya don't worry! One of my mum friends had a visible bump by 12 weeks, pero ang iba naman ay parang 5-6 months na bago makita ng iba, lahat depende sa body type, pelvic position, at kung first baby mo talaga. At 16 weeks ang some girls ay makikita na, pero kung slim ka or if your baby's positioned further back, it might not show much pa. The best thing is kung okay ang check-ups mo with your OB and baby's growing normally, then you're good, bawat pregnancy is really its own thing!
