Oo normal yan, mama! A few of us first-time moms noticed the same thing, ang bump natin parang lumalaki throughout the day from water, food, bloating, then bumalik small after matulog. At 17 weeks, ang baby pa lang so the bump can still be subtle, lalo na kung first pregnancy mo. Pero para makita mo ng clearer picture at ma-ease your mind, better i-check sa doctor mo para ma-confirm na lahat okay with baby's growth!
