Ay, alam ko yan feeling! A few of us din sa circle namin were worried ng same thing, pero honestly, tummy size really varies from mom to mom, kahit pareho ng weeks of pregnancy, kaya hindi lahat basehan. Since ang baby mo ay healthy weight based sa ultrasound mo (945g at 26 weeks sounds good), I'd say mas importante yun, pero since ikaw ang nag-aalala, worth checking with your OB lang at in your next visit para ma-confirm na lahat ay on track, just para sa peace of mind mo!
