can you still loose weight while pregnant?

It is said that in the first 2 months and 1/2, you will have terrible fatigue very terrible and couldn't get up it consisted of sleeping, eating ,sleeping pooping and peing and back to sleep, so of course you will gained some pounds before pregnancy. I hate to be this kind of style one day.
