Needs checking: First - make sure you are having regular bowel movements. Busy people often forget how important it is to avoid constipation. If there is no problem there I would make sure you have had a recent pelvic exam to make sure your ovaries are not enlarged. If there really is a dramatic physical change that comes and goes be sure to take pics to share with your doctor.
