I feel like I have been gaining a crazy amount of weight lately! Like 6 lbs in 3 weeks! Is this normal for the 3rd tri? I have been abnormally hungry, but have not been eating like a whole pie or anything - when I snack I try to eat veggies! Is there even anything to be done (aside from stay away from pie, et al) to try to moderate this. I know I will be gaining more weight, but this is seeming excessive!
