Normal Menstrual Cycle-Topic Overview

Continued

A change in hormone levels can affect your cycle or fertility. For example, teens tend to have low or changing progesterone levels. This is also true for women close to menopause. That is why teens and women in their 40s may have heavy menstrual bleeding and cycles that change in length.

Other things can change your cycle. They include birth control pills, low body fat, losing a lot of weight, or being overweight. Stress or very hard exercise also can change your cycle. Pregnancy is the most common cause of a missed period.

What common symptoms are linked to the menstrual cycle?

Some women have no pain or other problems. But other women have symptoms before and during their periods.

For about a week before a period, many women have some premenstrual symptoms. You may feel more tense or angry. You may gain water weight and feel bloated. Your breasts may feel tender. You may get acne. You also may have less energy than usual. A day or two before your period, you may start having pain (cramps) in your belly, back, or legs. These symptoms go away during the first days of a period.

When your ovary releases an egg in the middle of your cycle, you may have pain in your lower belly. You also might have red spotting for less than a day. Both are normal.

How can women take care of bleeding and symptoms?

You can use pads, tampons, or menstrual cups to manage bleeding. Whatever you use, be sure to change it at least every 4 to 8 hours. Pads may be best at night.

Many women can improve their symptoms by getting regular exercise and eating a healthy diet. It also may help to limit alcohol and caffeine. Try to reduce stress.

A heating pad, hot water bottle, or warm bath also can help with cramps. You can take an over-the-counter medicine such as ibuprofen or naproxen before and during your period to reduce pain and bleeding.
