A woman's period is also known as menstruation. Once a woman has gone through puberty, menstruation normally occurs on a monthly basis as a part of her normal cycle. During the menstrual cycle, a woman's body prepares for pregnancy. If the woman does not become pregnant, the body sloughs off some of the lining of the uterus in preparation for beginning again, leading to the "period."
Step 1
Looking for bleeding. During menstruation, the lining of the uterus as well as the menstrual blood is released through the vagina. It's common to notice the blood during urination.
Step 2
Be aware of menstrual cramps. Menstrual cramps are pain that affects many women just before and after their periods. Cramping can be a sign that your period is about to begin.
Step 3
Be aware of breast pain. Breast pain is actually a symptom of premenstrual syndrome, a condition that affects women one to two weeks before the symptoms of menstruation (bleeding) actually begin. Other symptoms of premenstrual syndrome include acne, bloating, joint pain, and a volatile emotional state, including mood swings.
Step 4
Watch for bleeding that lasts anywhere from three to nine days. This may be heavy or light.
Step 5
Understand what is "abnormal." Abnormal bleeding is mild spotting---you see a few drops of blood on toilet paper intermittently or very heavy---you soak through one pad per hour and the bleeding lasts many hours. This could indicate a problem, including cancer or an ectopic pregnancy. Women experiencing abnormal bleeding should consult a doctor.
