Aw, anak mo na talaga ang grabe! Around 33-34 weeks, the baby's really packing on the weight and amniotic fluid is also building up, so it's totally normal na parang biglang lumaki, a few of us moms noticed the same thing and it freaked us out din, pero doc assured us it's actually a good sign na healthy ang growth. Don't worry, you still have a few weeks left para mag-prepare, and honestly that rapid growth usually tapers off a bit after this point kaya enjoy lang ang pagiging bumpy while you can!
