I am at 33 week of pregnancy now. I can feel my body become heavier off late too. However I cannot sit still coz once I sit a bit longer, my butt becomes pain. And also the baby movement is a lot too when I am in sitting position. Hmmmm….this baby wants her mummy keep walking I think. Right now baby weight is 2kg, no wonder I feel a bit tire too after short distance walking. My prefer baby weight during giving birth is 3kg; hopefully this baby will gain the same weight as her sisters too.
