Uy, normal lang yan sa pregnancy, lalo na sa first trimester when your uterus is expanding super fast! A few of us moms experienced that tightness and hardness, especially after eating or drinking a lot, honestly, it's just your ligaments stretching and your baby bump starting to show up. That said, since you're a first-time mom and worried, best to mention it sa OB mo sa next check-up para ma-ease your mind completely, okay? Congrats on your first baby, mamsh!
