Hay, normal yan, mommy! Maraming amin na friends na nakaranas ng lip swelling during pregnancy kaya don't worry, it's usually just hormones and increased blood flow na ginagawa ng pregnancy. But since you're worried (totally valid!), mas better pa rin kung i-check mo lang with your OB just to be sure, lalo na kung may itching or difficulty breathing along with it, better safe than sorry, diba? In the meantime, try staying hydrated and avoiding spicy foods kung nakakaapekto sa iyo. Let us know what your doctor says!
