Aww congrats, mama! 30 weeks na kayo with baby boy, gaano kaligaya yun! A bigger bump at this stage is totally normal kasi ang baby boy ay talagang lumalaki na ngayon, plus the amniotic fluid, placenta, lahat nagdadagdag sa size, so don't worry about it! One of my mum friends said her bump was super big around this time with her son din, tapos he came out perfectly healthy naman, so you're doing great! Enjoy this phase kasi mabilis lang mawawala
