Uy, alam ko yan worrying talaga, pag ganyan ang dating ultrasound, naturally concerned ang mama. Pero honestly, kailangan mong i-follow up agad with your OB, ha, para sure lang sya kung may adjustment sa dating or if baby's growth needs monitoring. Ultrasound readings can shift slightly depende sa technician at positioning, pero yan ay dapat i-discuss ng doctor mo with you properly, wag mag-worry mag-isa. Sana makita mo na sya soon para may peace of mind ka na!
