I know as a preganant person, you will feel your body gets warmer than usual but its not fever, its just that our bodys will double its blood supply than usual. Migraines I have it too. My nausea tend to stop in 2nd trimester but I know every woman varries. HUNGER is ridiculous. So you have to try eat often but small and have plenty water, other2ise you might get nauseous. Hope this helps
