Dah 21 weeks bump kecil lagi

My weight before pregnancy, 40kg. Masa pregnant naik 6kg je. Badan i tak naik, just size perut. Everytime check up, i akan tanya pakar o&g i tu. Dia cakap its normal as long as the baby grow ikut weeks and healthy. My baby keluar pun normal weight 3.2kg. So dont worry k
