There is a chance you have a type of PMS at the beginning of your period. Physicians estimate that nearly three-quarters of women who have their period have signs of premenstrual syndrome, whether it be cravings, cramps, sore breasts or fatigue. However, premenstrual dysphoric disorder (PMDD) is different. It causes emotional and physical symptoms such as PMS and stress disorder, but women with PDT find that their symptoms are severe and often disrupt their daily lives, including their work, education, social life, and relationships.
