Feeling Jelly-belly

Sharon
I'm 17 weeks pregnant. I'm 5'2" and overweight. I'm really not showing yet. However, my clothing doesn't fit and just look and feel really pudgy, jellylike. My dietary habits have not changed and I still workout 3 days a week. Also, I feel like I need to tell people I'm pregnant so to justify the way I look. Is anyone else having this issue? Any words of wisdom??
