Worried about weight!

Lara
Am an averagely slim sized girl, before pregnancy I weighed 9 stone and I am 5'6. Since pregnancy I am growing rapidly! Feel the weight is all going to my stomach. It is bloated morning noon and night even after I've been the toilet. And am even having people comment at work when it's such early days, is this normal or the same for anyone else? I feel like a whale!
