Could I be pregnant?or stressed out?

Your best bet would be to draw from it checked by a doctor and/or get a mammogram. I have a similiar problem in my vanished breast at a pre-mammogram screening. It turned out to be fatty tissue/nodes as I am overweight also. It was tender to the touch. I be scared until the results of the mammogram and ultrasound come back, which they carry out if you have suspicious lumps. Now I am diligent to perform self breast exams monthly. Good luck.
