Aw, mama, I know how scary that sounds, lalo na first baby mo pa! Please schedule a follow-up with your OB as soon as possible para makita nila ang development ng baby mo, they'll explain everything clearly and give you the right next steps, kaya don't worry alone. A few of us mums have been through confusing ultrasound reports din, at palagi may reason behind it, pero kailangan talaga makipag-usap directly sa doctor mo para maintindihan mo ng maayos. Praying for you and baby, kaya mo yan!
