Almost 20 weeks and no weight gain?

Jennifer
Hey ladies! I'm 19w3d and haven't gained any weight yet. I lost maybe 2 lbs in the first trimester but gained it back, but haven't gained anymore. My last appointment, about a month ago, the dr told me it's ok that I haven't gained and that I would start around 18 weeks or so but I still haven't. My belly is definitely bigger and growing, none of my clothes fit lol but no weight gain. Anyone else?
