Pregnant or not? (Symptoms included)

Here lately My body had been acting TREMENDOUSLY different. 
​For about a good two weeks I've been bloated none stop , no cramping at all, but I've had a lot of lower back pain, and (TMI a little) my boobs have been very tender. They are swollen too, usually a 34 d but lately I've been wearing my old 38 d. I plan on testing tomorrow but I just want to know what you ladies think. What are the chances??
