Lately my periods have been late or a little early, but due to the fact of dieting and temporary job stress, I felt that they played factors in alternating my usual menstrual cycle. Now, I'm two weeks post period, but I'm experiencing extreme mood swings (I've never been one to cry at the drop of a hat or be mad rather quickly) and my nipples hurt like something crazy. Does anyone have an idea of what may be going on?
