Heavy set Pregnant 23 year old.

Okay, so I am 5'9 and weigh 239 lbs. I am in the 5th week and am so depressed about looking big and not pregnant. I didn't think I would ever have a child, so when I got my super dark positives a week before I was late, I was so shocked I stared at it for a good hour. Should I take belly pictures, or should I just keep it all hidden? :( :'(
