Anak, any changes sa tyan during pregnancy can be worrying, kaya best talaga to see your OB about this, especially if it's sudden or uncomfortable. Maraming bagay ang pwedeng maging normal sa pregnancy, pero need lang i-check ng doctor para sure ka. A few of us moms noticed ang weird movements and swelling din nung pregnant kami, pero lagi kaming nag-confirm sa doctor para peace of mind. Don't hesitate to call your clinic or go in, yan ang best way to know kung okay lang baby mo. Take care!
