Ay mama, napakabasa ko na ang ganitong concern from a few of us sa mommy group ko, at honestly dapat talaga i-check mo yan with your OB kasi it could be a few different things, could be postpartum swelling pa lang, or something na kailangan ng proper evaluation para ma-rule out kung normal lang or may kailangan ng treatment. Don't worry though, most likely it's nothing serious, pero better safe na lang especially since fresh pa lang from delivery ang katawan mo, kaya make that appointment agad ha!
