To much weight gain...

Pre pregnancy I weighed around 114 I'm 5'5. My first OB appt I weight 118 at six weeks and four days. I'm currently 140 lbs at 26 and 5 days.. My last appt they showed me my weight gain on a pretty little chart. I was gaining normally within range. My pregnancy has been easy no morning sickness for me to loose or struggle with weight.. overall I've gained 23lbs but in my defense I was not a healthy eater before. I was lucky if I had a single meal all day drank nothing but pop and snacks. I now eat every meal and snack on fruits between. Drink a large amount of water and milk and reward myself with juice. I passed my 1hr sugar test. I just honestly don't see the issue.. I was stressing about what I was eating.. then they put me on iron because I'm anemic.. I'm stressing over gaining weight. I've decreased my meal intake and skip a snack. My other friends said they said a large amount in four weeks.. My large gain was in six weeks.. I work on labor and delivery and the other doctors said I was underweight and shouldn't be conconered..
