What is this I'm Feeling?

Today I am starting to feel like something else is going on with my body. It's funny because I dont feel pregnant. Some things that are going on are, tired all the time, last night my boobs hurt to the touch,(never happened before), loss and gain of appetite, smells increased even more, cramping. I dont know if my Aunt Flo is just coming to visit. But oh how I wish its because I'm pregnant!
