Hi hon! Congrats sa pregnancy! Para sa gender prediction at anything about your ultrasound results like that "posterior lowlying grade 1", kailangan mo talaga makipag-usap directly sa doctor mo, okay? They're the ones na makakasagot ng tama based sa actual ultrasound images at findings. Ultrasound results can be tricky to interpret, and what you're reading might need proper medical context, lalo na kung may medical terms involved. Don't worry, most OBs are super willing to explain everything in detail, so just ask during your next visit or call their clinic!
