How Long Does A Teenage Period Last

What Causes A Period

Dating Advice : How Long Do Teenage Relationships Last?

A period happens because of changes in in the body. Hormones are chemical messengers. The ovaries release the female hormones and . These hormones cause the lining of the uterus to build up. The built-up lining is ready for a fertilized egg to attach to and start developing. If there is no fertilized egg, the lining breaks down and bleeds. Then the same process happens all over again.

It usually takes about a month for the lining to build up, then break down. That is why most girls and women get their periods around once a month.

The Source Of The Issue

Long periods can be the result of a variety of factors such as health conditions, your age and your lifestyle.

Underlying health conditions that can cause long periods include uterine fibroids, endometrial polyps, adenomyosis, or more rarely, a precancerous or cancerous lesion of the uterus. A long period can also result from hormonal imbalances or a bleeding disorder.

Many women struggle with long and heavy periods for years without knowing there are ways to manage and improve their symptoms. I encourage all patients to seek out medical care if they have questions about their menstrual cycle or other gynecologic issues.

The first step to managing long periods due to a specific condition is to treat it. This can include things like removing an endometrial polyp or correcting hypothyroidism. Hormonal contraceptives are commonly used to help regulate abnormal cycles resulting from a wide variety of causes. Most of these methods take three to six months before youll notice some improvement.

Period Bleeding Thats Cause For Concern

Your daughter probably doesnt want to discuss her periodwith you. But talk to her if you notice that she:

  • Is going through a huge stack of pads each month
  • Has periods that last longer than 10 days
  • Has heavy bleeding throughout her entire period

If she does have a bleeding disorder, you might notice theseother signs as well:

  • Blood loss when a baby tooth fell out or whilebrushing teeth
  • History of significant bleeding during minorsurgery
  • Family history of bleeding disorders or heavyperiods

Some unlucky women just have heavier periods than others. But if you have any concerns, its worth taking your teen to see a doctor even if it means risking some heavy-duty eye rolling.

Three Phases Of The Menstrual Cycle

How Long Does Period Pain Last Before Period

The phases of your menstrual cycle are triggered by hormonal changes.

Menstrual period

On Day 1 of your cycle, the thickened lining of the uterus begins to shed. You know this as menstrual bleeding from the vagina. A normal menstrual period can last 4 to 6 days.

Most of your menstrual blood loss happens during the first 3 days. This is also when you might have cramping pain in your pelvis, legs, and back. Cramps can range from mild to severe. The cramping is your uterus contracting, helping the endometrium shed. In general, any premenstrual symptoms that you’ve felt before your period will go away during these first days of your cycle.

Follicular phase

During the follicular phase, an egg follicle on an ovary gets ready to release an egg. Usually, one egg is released each cycle. This process can be short or long and plays the biggest role in how long your cycle is. At the same time, the uterus starts growing a new endometrium to prepare for pregnancy.

The last 5 days of the follicular phase, plus ovulation day, are your fertile window. This is when you are most likely to become pregnant if you have sex without using birth control.

Luteal phase

This phase starts on ovulation day, the day the egg is released from the egg follicle on the ovary. It can happen any time from Day 7 to Day 22 of a normal menstrual cycle. During ovulation, some women have less than a day of red spotting or lower pelvic pain or discomfort . These signs of ovulation are normal.

Medicine For Menstrual Pain And Bleeding

Try a non-prescription medicine to help relieve your pain and bleeding. Start taking the recommended dose of pain reliever when symptoms begin or 1 day before your menstrual period starts. If you are trying to become pregnant, talk to your doctor before using any medicine. Be safe with medicines. Read and follow all instructions on the label.

  • Non-steroidal anti-inflammatory drugs , such as ibuprofen , reduce menstrual cramps, pain, and bleeding by lowering the level of the hormone prostaglandin.
  • If NSAIDs do not relieve the pain, try acetaminophen, such as Tylenol.
  • Take the medicine for as long as the symptoms would normally last if you did not take the medicine.

Be sure to follow all labels and directions. Do not take aspirin if you are younger than 18 because of the risk of Reye syndrome.

When To Get Checked Out

Normal cycles last between 24 to 35 days. Some teens might have shorter cycles of only 21 days, and others might go as long as 45 days between periods. Adults can have a range of between 21 to 35 days. See a doctor if your cycle falls outside of these ranges. Also, if youve been menstruating for more than two years and your period hasnt become regular, visit a healthcare provider.

Being sick or under stress can cause a delayed period or for you to skip it altogether. However, if you miss a period and are sexually active, definitely get checked out for a possible pregnancy. Also, visit a healthcare professional about your period if:

  • You havent gotten your first period by age 15
  • You dont menstruate for more than 90 days
  • Your periods start to be very irregular after having previously been regular
  • Your period lasts for more than seven days

What Controls The Menstrual Cycle

Your hormones control your menstrual cycle. During each cycle, your brain’s hypothalamus and pituitary gland send hormone signals back and forth with your ovaries. These signals get the ovaries and uterus ready for a pregnancy.

The hormones estrogen and progesterone play the biggest roles in how the uterus changes during each cycle.

  • Estrogen builds up the lining of the uterus.
  • Progesterone increases after an ovary releases an egg at the middle of the cycle. This helps the estrogen keep the lining thick and ready for a fertilized egg.
  • A drop in progesterone causes the lining to break down. This is when your period starts.

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.

    How Does Ovulation Relate To Periods

    Ovulation is the release of an egg from the ovaries. The same hormones that cause the uterus lining to build up also cause an egg to leave one of the ovaries. The egg travels through a thin tube called a fallopian tube to the uterus.

    If the egg is fertilized by a sperm cell, it attaches to the wall of the uterus, where over time it develops into a baby. If the egg is not fertilized, the uterus lining breaks down and bleeds, causing a period.
