Everyone has a certain connection to a woman either as a sister, co-workers, mother, wife or others. The premenstrual syndrome(PMS) refers to the various symptoms that occur between the weeks of ovulation and the menstrual cycle. It is still unknown why some women have PMS and other women don’t, however, PMS symptoms are linked to changing levels of serotonin, progesterone and estrogen. PMS symptoms start five to eleven days before menstruation and go away once menstruation begins just as the name implies “premenstrual” syndrome. However, it is normal for premenstrual symptoms to change over time as your own body matures.
