No appetite and weight gain has finally stopped.

So Ive been gaining rapidly this whole 33 weeks. Im up 47 lbs and my Dr mentioned at my last appointment (2 weeks ago) to be aware of how much I eat and to not over do it. It hasn't been a problem because I literally don't feel much like eating anymore and thats odd for me. I think its due to stress because Lord knows my life is full of it right now. I weighed myself this morning and Im actually down about a pound. Is that OK? If baby is supposed to be gaining approximately 1/2 lb per week does that mean Im loosing weight or shes not growing? I see the Dr on Thursday so I'll express my concern just curious what your thoughts are or if your in a similar situation!
