Haven't gained any weight

Brittany
My whole life I've struggled with "being large" and when I got pregnant and was told to try to start gaining weight I thought "oh this will be easy" but now today at my appointment I was told that I've actually lost weight since getting pregnant despite trying to gain weight. At the same time I know I've gotten bigger because most of my normal clothes don't fit and I'm not even sporting a noticeable bump!
