Oo normal yan, lalo na ngayon na lumalaki ang baby mo, marami sa amin na moms na nakakasuffer ng ligtas na tummy aches during pregnancy, usually dahil sa stretching ng ligaments. But since this is your first time at important talaga, best to mention it sa OB mo next visit para ma-check niya and ma-rule out anything na kailangan ng attention, mas luwas ang loob if the doctor confirms it's all good! Praying for you and baby!
