Weight gain during pregnancy?

Your weight gain is fine. The same thing happened to me. I lost 6 lbs when I first got pregnant, had gained it back by 18 weeks when my belly popped, then I started piling on the weight out of no where. I gained a total of 65 lbs while I was pregnant even thought I was eating right and exercising as often as I could. I gave birth 13 days ago and I've lost 45 lbs already because so much of the weight I gained was water weight. Everyone gains weight differently, but it's really nothing to worry about.
