Ay, ganyan talaga ang ultrasound sometimes, meron kasing difference depende sa machine at kung paano sinusukat ng doctor, hindi ka nag-iisa dito! A few of us moms experienced the same discrepancy, so don't stress too much about the 1-2 week difference, yan ay normal pa within range. For the height ng tyan mo naman, basta okay ang movements ng baby at walang complications ang doctor nabanggit, usually okay na yan, bawat mama carries differently! Pero para sa peace of mind mo talaga, better check with your OB about the measurement gap and kung okay pa ba lahat with baby's growth, kasi they'll give you the most accurate picture based sa overall health mo at ng baby.
