Oo normal yan, lalo na ngayong first trimester ka pa lang! Ang ligament mo (round ligament) lumalaki at umuunat habang lumalaki ang baby, kaya minsan may sakit sa isang side tapos sa iba. A few of us mums noticed the same thing around that time, one friend said it felt like a sharp pinch, another had a dull ache. Pero if the pain gets really intense, hindi na kaya, or may spotting pa, better check with your OB para peace of mind lang talaga. Congratulations sa baby mo!
