Showing the symptoms of PMS, or premenstrual syndrome, is the most telling sign that you are about to begin your period. Common PMS symptoms include acne, fatigue, cravings, tenderness of the breasts, headache, bloating, anxiety, depression and muscular pains, as listed by WebMD.
PMS symptoms occur one to two weeks prior to the beginning of your period, as Women's Health explains. Not all women claim to experience PMS because not all women experience it in the same way, so you may only experience one or two of the PMS symptoms before beginning your period. However, you may experience most of them to the degree that they interfere with daily activities.
It isnt clear what the cause of PMS is, but there are a lot of factors that can make it worse. Stress and emotional problems cause an imbalance of hormones and often lead to worse emotional PMS symptoms, according to Women's Health. Drinking things that alter your mood, such as caffeine and alcohol, can also lead to an imbalance in hormones and to exhaustion.
Deficiencies in certain nutrients can also lead to worse PMS symptoms because the body depletes more vitamins and minerals as it prepares for the menstrual cycle. Eating large amounts of salty food can lead to bloating because the salt causes the body to retain water, as Women's Health explains. This can also dehydrate you and cause headaches.
