26 Weeks Pregnant, Can't Stand To Eat Actual Meals, Cravings Sweets?

hey, I'm 26 weeks pregnant. and lately, I havn't been as interested in food as usual. Like just certain types of foods tho. Mainly all the meal type, foods I just can't stand to even think about. things I usually always ate for dinner in the past, such as spaghetti, macaroni and cheese, mashed potatoes, meats, pasta's, ravioli's, etc... with my first pregnancy, I never really developed food adversions this late in the pregnancy. and now, every thing sounds terrible in the last couple weeks. the only foods that I really want to eat, that I crave, are more sweets, like candies, cakes, cookies, ice cream like crazy, some fruits, breads, such as bagels, and pop tarts. I can't stand to eat actual meals, so I've just been snacking more on random snack type foods. why is this, do you think my appetite will go back to normal soon?
