try to measure fundal height. it should be near 28cm. also, verify size of baby by ultrasound. my OB measured my tummy kaya nia nasabi na maliit kaya she requested for ultrasound. sakto ay for CAS naman. maliit ng 1week si baby. kaya she advised me to eat more protein rich food. kumain na rin ako ng marami. pasok sa normal ang weight ni baby paglabas.
