Girl or boy talaga ang hirap basahin sa ultrasound, lalo na kung mahigpit ang position ng baby! One of my mum friends couldn't find out with her second because the baby kept crossing legs, haha, kailangan ulet ng follow-up scan. Best to ask your OB kung confident sila sa reading, or kung gusto mo talaga alam, set up another appointment when baby cooperates na. What did your doctor say?
