its normal . i experienced that too. i dun feel pregnant when im pregnant w my 2nd .. maybe because we already had our 1st to occupied us . time tend to go fast and next thing you know you are already in labour . just enjoy this moment and spend time with th 1st child as much as you can before you will be busy w th 2nd . btw have a smooth delivery mummy! oh ya rest as much as you can .😀
