On the second ultrasound September 27 at ngayon lastest September 23.. yung OB ko sinusunod nila is yung first ultrasound ko pero nakabahala kasi on my latest ultrasound sept. 23 estimated fetal weight is 3.2 grams.. natatakot ako pag october pa talaga sya lalabas baka sobrang laki na talaga ni baby 🥲 May I ask your opinion about this?
