Every person and every pregnancy is different. With my first baby I gained 45lbs starting at about 10 months along. I put the most weight on rapidly in the 3rd trimester. I am now expecting my second baby 24weeks along now and only gained 2lbs so far. My advice to you is don't worry, eat healthy, and drink up on water. Your body knows best, listen to it and baby will be just fine. Hope all goes well for you and baby to be. Good luck momma!
