Anyone else

Anyone else drink these? I have a stomach problem where food doesn’t actually go into my stomach and I get sick after eating. I’m down over 30lbs and barely half way through my pregnancy. My doctor said to drink things with calories and protein since I keep down liquids just no solids. But not sure if this is okay? Im also gonna start making smoothies too, just not sure if I should put protein powder in it as well. I’m not sure if protein shakes are okay durning pregnancy
