In my experience being pregnant twice before my pouch and once after this is a symptom I had with all three. It sounds like it is just your body’s reaction to pregnancy (yay! lol) with all three of mine I had to be constantly munching on something or I’d get incredibly nauseas. It was particularly bad in the beginning. I hope your symptoms level off soon! But if they don’t, don’t let it stress you. Trust your body is asking for what it needs… it takes a LOT of energy to grow a whole human!
