What is a period?

Signs your period is coming include tender breasts, headaches, abdominal cramps, muscle aches, lower back pain, fatigue, bloating, joint pain, acne, and diarrhea or constipation.

A period, also called menstruation, is when your body removes the buildup of the lining of your uterus. This buildup of menstrual blood and tissue flows out of your vagina. The day your period starts is the first day of your menstrual cycle, which lasts until the first day of your next period.

Recognizing the signs that your period is coming helps you prepare to deal with the symptoms your body goes through during your menstrual cycle.

Signs of a period

You will probably feel certain symptoms in the days leading up to your period, including:

Tender breasts

Changes in hormone levels before menstruation can cause pain, swelling, and tenderness in your breasts before your period.

Headaches

When estrogen levels drop before your period, it can trigger headaches, including migraines.

Abdominal cramps

Menstrual cramps are throbbing, cramping pains caused by excessive chemicals produced by your uterus before your period that make the muscles in your uterus tighten and relax.

Muscle aches

You may also feel pain in your muscles, resulting in body aches.

Lower back pain

The pain caused by your abdominal cramps can also extend into your lower back, giving you lower back pain in the days leading up to your period.

Fatigue

Hormone changes before your period can affect your brain chemistry, making you feel more tired before menstruation. This can also cause sleep problems, which can contribute to your fatigue.

Bloating

Changes in your hormones can cause you to retain water before your period, making you experience bloating.

Joint pain

Estrogen is a hormone that helps control joint pain, but right before your period, your estrogen levels go down. This can increase your joint pain.

Acne

Changes in hormone levels can make your body produce more oil, which clogs your pores. This can cause you to develop pimples before your period begins.

Diarrhea or constipation

Your digestive system can experience changes when your period is coming, causing you to have diarrhea or constipation.

Premenstrual syndrome (PMS)

Premenstrual syndrome, or PMS, includes the range of emotional and physical symptoms you may experience in the days leading up to your period. In addition to the physical symptoms listed above, you may also experience mood-related symptoms. These can include:

Irritability
Trouble focusing
Anxiety
Sadness
Anger
Lack of interest in talking to others
Crying spells

Causes of periods

During your menstrual cycle, one of your ovaries releases an egg. At the same time, the lining of your uterus builds up to prepare for a possible pregnancy. But if you don't get pregnant, your estrogen and progesterone hormone levels fall and tell your body to start your period, flushing the buildup of menstrual blood and tissue through your vagina. Bleeding can last 2 to 7 days.

While most menstrual cycles are 28 days long, women experience different cycle lengths. Your menstrual cycle can also be altered by different factors, including:

Birth control pills
Pregnancy
Breastfeeding
Disordered eating
Extreme weight loss
Excessive exercise

You may get your first period between the ages of 8 and 15 and have a menstrual cycle longer than 38 days. As you get older, your menstrual cycles usually become more regular, but they may become irregular in your 40s. Once you experience menopause, your menstrual cycles end.

When to see the doctor for your period

If your period lasts more than 7 days, if you experience strong pain, or if you have a heavy menstrual flow and need to change pads or tampons every hour, discuss your symptoms with your doctor.

You should also call your doctor if:

You haven't experienced a period in 90 days
You have periods more often than once every 21 days
You have periods less often than once every 35 days

Missed or irregular periods can be a sign of stress or a medical condition. Talk with your doctor to find the cause of your irregular periods and how to treat it.

Tests for periods

If you have abnormally heavy menstrual bleeding, your doctor may conduct a pelvic exam, rectal-vaginal exam, pelvic ultrasound, or other tests to learn the cause of your excessive bleeding. If you miss your period, a home pregnancy test will let you know if you're pregnant. However, if it comes back negative, a doctor can conduct a blood test to determine if you're pregnant or not.
