Hey mama, yan talaga ay common sa 29 weeks kasi lumalaki na ang baby and your body's shifting the weight around, ligaments are stretching and your pelvis is loosening up para sa delivery. Pero since it's radiating down to your legs, better check with your OB para masiguro kung hindi ito sciatica or something else na kailangan i-address, lalo na kung nakakaapekto sa sleep or movement mo, mas better safe than sorry, diba?
