Oo, super normal yan sa pregnancy, lalo na pagdating sa second at third trimester! Ang metabolism mo tumaas, kaya ang katawan mo nagugutom ng mas mabilis, at pag delayed ang kain talaga nakakasakit ang tiyan dahil sa acid buildup sa stomach mo. A few of us had the same experience, what helped was kumain ng small frequent meals instead of waiting for big meals, at laging may snacks handy like crackers, banana, or nuts para hindi ma-trigger ang acid. Pero since 9 weeks ka pa lang, check with your OB just to make sure everything's okay, especially if the pain is intense or may iba pang symptoms, baka kailangan lang ng dietary adjustment or something prescribed para ma-manage better. Ingat at take care of yourself!
