Oo naman, normal yan sa first trimester! Ang hormonal changes talaga ay nakakaapekto sa digestion, kaya maraming preggy friends ko na may diarrhea o constipation during early pregnancy, it's one of those things na hindi palaging sinasabing major sign pero sobrang common. Pero kung matinding or may fever, best na i-check mo sa OB mo para sure lang, lalo na importante ang hydration during pregnancy.
