17 weeks belly???

Normal lang. Mostly by that week nasa puson pa talaga si baby. By 20 weeks onwards pa magiging noticeable ang bump. As long as okay naman ang result ng mga ultrasounds mo, you don't have anything to worry about.

Iba iba naman po size talaga. Depende din kasi sa body ng mommy at depende din po kung pang ilang pregnancy na.
