Ay, first-time mommy ka pa lang kaya normal mag-worry! Listen, every pregnancy is different talaga, some tummies are softer, some firmer, at it changes as baby grows. Pero kung nag-aalala ka talaga, especially kung may pain or kung parang hindi normal ang galaw, better to call your OB agad lang para peace of mind mo. A few of us moms noticed na the more weeks go by, the tighter and rounder everything gets, pero better safe than sorry sa ganito. Huwag mag-overthink, your doctor lang ang magbibigay ng best answer based sa checkup!
