I read that weight gain in the first trimester is not necessary & that 25-30lbs on average is all that is required for a healthy pregnancy. This coupled with comments from family & other pregnant friends have me believing I should not be gaining weight at this stage. However at just over 8 weeks pregnant I have gained 4lbs. I am pretty petite & don't gain weight easily so this seems substantial. I suspect this is mainly due to an increase in carbs (the only thing to make nausea bearable so far) as these were a pretty limited part of my diet previously. Am I crazy to be concerned about this? Should I just go with the flow & hope that things even out next trimester? What was your experience?
