Anyone else??

Anyone else overweight before finding out tmyou were pregnant?  I'm having a hard time figuring out what to do in order to not gain too much weight. Plus there's some self esteem issues that are popping up the last few days. I'm bloated and feeling huge compared to where I think I should be. I'm 5'3" and weight around 155. Super scared that I'm not healthy enough to do what I need to for my baby but also very self conscious about how I look and what I can do to possibly tone my arms and legs while pregnant.
