Uy mama, that's something you really need to talk to your OB about ASAP, hindi dapat mag-self-diagnose tayo dito, especially at 37 weeks na kayo.
A few of us moms have had babies na medyo mas maliit o mas laki than expected, pero ang growth measurements can mean different things depending sa case, at kailangan talaga ng doctor mo na mag-explain kung ano ang best next steps para sa inyo. Please don't worry too much, your OB will know exactly what to do, okay? Rooting for you and baby!
