Pregnancy Weight

Mommies, I'm currently 23 weeks pregnant. Concern ko lang is simula ng nag start ako with my prenatal check up when I was at 6 weeks, I'm just weighing 43 kls. Then last check up ko earlier this month, when I was at 21 weeks, nadagdagan lang ng half kilo weight ko. Dapat ko po itong ikabahala? #firsttimemom #Junebirthclub
