Congratulations, mama! Usually around 3-4 months na makikita ng iba ang baby bump, pero honestly it depends talaga, some of my mum friends showed earlier, iba naman parang 5-6 months pa lang obvious. First-time moms usually show a bit later than second or third pregnancies kasi ang uterus mo ay unstrengthened pa, but you'll definitely feel yourself getting rounder soon! Enjoy the glow phase na yan before the bump gets really big
