So after entering my second trimester, my nausea was better for about the first week. Now in my 15th week, the past 3-4 days, my nausea seems worse than ever before. I feel sick before I eat and then as soon as i'm done eating. My diet the past week has consisted of an egg sandwhich for breakfast, a turkey burger for lunch, maybe a grilled cheese for a snack, and our dinner always has 2 veggies. I don't understand what's going on and am wondering if I should go to the hospital.
