Aww mama, that shooting pain down to your legs ay common sa pregnancy, pero para sa peace of mind mo talaga, better to mention it sa OB mo sa next check-up, lalo na if it's getting worse or affecting how you move. A few of us pregnant moms had similar pains, and iba-iba ang causes nito, so best na professional can rule out anything serious and give you the right exercises or support. In the meantime, mag-rest ka ng maayos, avoid heavy lifting, at try prenatal pillows para mas comfortable ang sleeping position mo, life-changer yan! God bless your pregnancy, mama!
