How to track your menstrual cycle (for teenage girls)

Learning to track your menstrual cycle can be important for several reasons. This first lets you know the average length of your menstrual cycle so you won't be surprised when your period arrives.

Part 1 of 3: watch your cycle

Track Your Menstrual Cycle Step 1

Step 1. Write down the first day of your period

The first day of your period is the day you start your period. Your cycle runs from the first day of your period until the first day of your next period. The length of a cycle varies with each woman, but it usually lasts between 21 and 35 days. The bleeding usually lasts between 2 and 7 days.

  • Count the number of days between your period and the duration of your bleeding.
  • If you started having your period in the past two years, your cycle may last longer. Your cycle should get shorter and more regular over the years. Your cycle length will also change during perimenopause, which is the time you approach menopause.
  • The frequency and length of your cycle may also vary if you are using birth control methods (for example, the birth control pill).
  • Your ovulation period is usually between day 11 and day 21 of your cycle. This is the time when you are most fertile and most likely to get pregnant if you have sex.

Step 2. Keep track of your physical symptoms

Write down the amount of your menstrual flow and any pain you feel. Try to include as much detail as possible. In addition to tracking your physical symptoms, watch the day of your cycle when they appear. For example, do you have cramps a few days before your period starts?

  • How many sanitary napkins or tampons did you use?
  • Do you have cramps? Do you have any cramps in your lower abdomen or lower back?
  • Do you feel pain in your breasts?
  • How does your vaginal discharge change during your menstrual cycle?
  • Do you have diarrhea or loose stools during your period? (This is a common symptom).

Step 3. Pay attention to your emotions

Many women experience emotional changes as their hormones fluctuate. You may experience anxiety, depression, mood swings, irritability, loss of appetite, or crying attacks. These symptoms usually appear before the cycle begins. Try to write down the days you have these symptoms.

  • Also watch out for any other stressors that may affect your mood. This can help you know if you are anxious about your period or if you are worried about a project at school.
  • If these symptoms appear around the same time each month, it is likely that they are related to your menstrual cycle.
Create a Study Schedule Step 3

Step 4. Repeat this process every month

Follow the progress of your menstrual cycle for a few months in a row to get to know your body. You should start to see similar physical and emotional symptoms and situations each month. Note each change that occurs from month to month.

  • It is normal that there are variations. You could have a period for five days in one month and three days the following month.
  • What is normal for you may not be normal for someone else. Don't worry if your cycle is different from another girl you know. Look for a pattern in your own cycle.
  • Using the pill, hormonal intrauterine device (IUD), contraceptive implant, contraceptive patch, or contraceptive injection may result in less heavy periods, but this is completely normal.

Step 1. Note important days on a calendar

If you want to track your menstrual cycle the old fashioned way, take a calendar and mark the days with a pencil, pen, marker, or highlighter. You can use different colors, symbols or stickers to mark the start and end of your menstrual cycle, the length of your cycle, or the days when your physical or emotional symptoms started. Try to put in place a clear system that works for you.

  • If you don't want to put too much information on your calendar, you can keep a diary to mark your physical and emotional symptoms and only use the calendar to mark the start and end of your menstrual cycle.
  • If you don't use your calendar too often, keep it somewhere you'll remember. It can be useful to hang it in your bathroom or put it next to your mirror.
  • If you value your privacy and don't want people to see your information, make a small, inconspicuous sign on the calendar (like a cross, circle, or color) that only you can understand.

  • Clue is a free app for iPhone and Android and is among the most recommended apps.

After entering your information for a few months, this tool will use algorithms to predict the date of your next period and when you ovulate.
  • Period Tracker Lite is another recommended application that will allow you to track your menstrual cycle. With this app, you can use icons to describe your mood rather than entering information. Period Tracker Lite is available for iPhone and Android.
