Smaller than the gestational age

Hi Mommies, question? Ano yung finollow ng OBGYNE niyo sa EDD niyo, was it your LMP or your first ultrasound? I have this experience wherein the ultrasound doctor asked kung “saan nagbase yung ob mo, sa first ultrasound mo?” Mukha maliit yung baby, I guess? Is that normal? Or should I be worried coz the baby is smaller? Thank you in advance. Super stressed ako sa comment ng nag ultrasound sakin. 😭#firstbaby #firsttimemom
