Weight loss ....

I’m 17 weeks, and in total now I’ve lost about 11-13lbs. I have had no morning sickness and have had a pretty easy pregnancy so far. My issue is I just can’t get myself to eat a lot. I am not hungry hardly ever or if I am hungry and eat too much I get nauseous. I’m a bit overweight anyways which is why he wasn’t too concerned to begin with. My doctor said in the beginning it was ok, but now he’s telling me I should be in the process of gaining weight not still losing. Has anyone not gained much weight throughout their pregnancy and everything was fine?

(Of course I lose weight while pregnant, but after all those time trying pre-pregnancy nothing worked 🤦🏼‍♀️ haha)
