14 wks and ive lost weight

Before pregnancy I was 157

At 9wks I was about 150/151

My 11wk/12wk first prenatal appointment I was on track at 153

I went to see a nutritionist yesterday and I’m now 149. She suggested I eat more and eat more healthy snacks in between.

I only had morning sickness for less than a month in the beginning, I occasionally get sick here and there but that’s when I’m super bloated. But I could have sworn I was eating like a mad man.

I’m now 14wks. Has this happened to anyone else? I’m not worried, I’m just not feeling the whole I need to eat more part, I think I eat enough and I’m already obese for my height and age. I’d like to maintain a certain weight and avoid gestational diabetes
