WHAT YOU NEED TO KNOW:
What is menstruation?
Menstruation is your monthly period. During menstruation, your body releases hormones (special chemicals) to help prepare for pregnancy. As the levels of hormones increase, the lining of your uterus becomes thicker. During the middle of the menstrual cycle, ovulation occurs. Ovulation is when the ovaries release an egg. If the egg does not get fertilized, it passes through the uterus and out of the body. The lining of the uterus, together with blood and mucus, breaks down and sheds. This blood flow passes through the vagina and causes your monthly period.
When does menstruation begin and end?
Some girls may have their first period at 9 years of age, while others begin at 16 years or older. Most women start to have a monthly period at about 12 years. Menopause is the time in a woman's life when monthly periods stop. This usually occurs at age 50 or older.
What happens each month?
Each period may last for 2 to 7 days and can be light, moderate, or heavy. The total amount of blood loss may be 1 to 4 tablespoons (20 to 60 milliliters) for the whole menstrual period. This amount may be different among women and it may be different for you from one period to another.
What symptoms may I feel during menstruation?
Premenstrual syndrome (PMS) is a group of physical, emotional, and mental changes that you may have before your monthly periods. These symptoms are caused by an increase in hormones. They include headache, dizziness, bloating, and nausea. You may also feel very tired, have breast swelling or soreness, and problems with sleep. You may have mood changes, such as feeling grumpy, sad, or emotional. These symptoms usually go away when your monthly period starts. Ask your caregiver for more information about PMS and how symptoms can be controlled.
What conditions may prevent menstruation or make it irregular?
Your menstruation may be irregular for 2 to 3 years after your monthly period begins. Other things that can prevent menstruation or make it irregular are:
- Pregnancy or breastfeeding: Pregnancy causes monthly periods to stop. A women who breastfeeds her baby full-time may not have a period until she stops breastfeeding.
- Ovulation disorders: These include poorly-controlled diabetes, Cushing's syndrome, thyroid disorders, and other conditions that affect hormone levels. Polycystic ovarian syndrome (PCOS) is another condition that may cause irregular periods. When you have PCOS, your ovaries produce higher levels of male hormones than female hormones. PCOS may cause irregular menstrual periods.
- Other causes:
- Eating disorders such as anorexia (eating very little) or bulimia (bingeing and purging)
- Weight problems, such as being overweight or underweight
- Exercising too much
- Previous surgeries on the abdomen or pelvis, such as surgery to remove the uterus
- Stress or being emotionally upset
How can I care for myself during menstruation?
- Use tampons or sanitary napkins: Read the instructions carefully or ask how to use tampons or sanitary napkins.
- Always wash your hands before you put in a new tampon to prevent infection. Wash your hands after you change pads or tampons.
- Change your pad or tampon about every 3 to 4 hours to keep the blood from soaking through your clothes. Change your tampon often to help prevent toxic shock syndrome (TSS). This rare condition is caused by a bacteria and may be related to leaving a tampon in for a long time. Alternate tampons and sanitary napkins during the day. Use sanitary napkins at night. This may help prevent TSS.
- Wrap toilet paper around the pad or tampon and throw it in the trash. Do not flush the pad or tampon down the toilet. It can block up sewer lines.
- Rest, exercise, and eat healthy foods: These are some ways to help control symptoms of PMS. Your caregiver may also suggest other ways to manage PMS.

- Your periods used to be regular and then became irregular, or your period lasts for more than 7 days.
