Relax, its suppose to be a rollercoaster! And, if you are eating well, just listen to your body. If you are hungry, then eat. You need to reconcile yourself to the idea that you WILL gain weight. Again, you are supposed to. I completely understand not wanting to gain TOO much though, I have that same worry. But you can't let it stress you. Stress is extremely bad for the baby and has an impact on their development. Try to do anything you can to relax. If the working out is helping with the stress then good for you! Sometimes jumping on the treadmill is enough to relax me. And, most importantly, try to enjoy this time. It is a time denied to some women and it goes by oh so quickly, even if it doesn't feel like it at the time. Use the boards here as a resource, you are definitely not alone. Good luck with it all and best wishes!
