Alam ko na nakakakabahala yan lalo na first time, pero yan talaga normal sa pregnancy, ang uterus mo lumalaki kaya parang hard or tight ang tummy mo, lalo na kapag gumagalaw or nag-stretch ka! Pero if it's painful or sobrang frequent, better to mention it sa OB mo just to be sure lang, okay? You're doing amazing sa first pregnancy mo, and asking questions like this shows you're already a thoughtful mom.
