I am 12 weeks and until now I have stayed pretty steady at my pre-pregnancy weight just gaining and losing the same pound or two. This week I am down 3 lbs and am not hungry. I get nauseous if I eat anywhere near the amount I use to at a regular meal and for the last week very little has even looked good enough for me to eat. I'm 5'7 and weighed 142 before I got pregnant so I do need to gain some weight for a health pregnancy. I feel bad complaining because I know a lot of you are trying not to gain too much weight but I'm starting to get a little worried. Is this just a stage? Anyone have any advice?
