Ay, normal lang yan, mama! At 13 weeks ang belly mo ay nagsisimula na talaga mag-show, lalo na kung second pregnancy mo or kung payat ka naturally, mas mabilis makikita ng iba. Marami sa mga kaibigan ko na ganyan din, at ng doktor nila sabi it's totally expected sa stage na yan ng pregnancy.
That said, if you're worried about how fast or how big it's getting, better check in with your OB lang para peace of mind, they can confirm kung lahat ay on track, especially if first time mo mag-worry dito.
