Missed or late periods happen for many reasons other than pregnancy. Common causes can range from hormonal imbalances to serious medical conditions. As your body goes through the transition, your normal cycle can become irregular. However, a healthy menstrual cycle can range from every 21 to 35 days. Stress can throw off your hormones, change your daily routine, and even affect the part of your brain responsible for regulating your period — your hypothalamus.

Even though girls get their periods on a cycle, that cycle can take different amounts of time each month. For example, a girl might get her period after 24 days one month and after 42 days the next. These are called irregular periods. Irregular periods are very common, especially in a girl's first few years of getting her period. Most girls get their first period between the ages of 10 and 15, but some get it earlier and some later. The first period is known as menarche pronounced: MEN-ar-kee. A girl's monthly cycle is the number of days from the start of her period to the start of the next time she gets her period.
8 Reasons Your Period Is Late When You're Definitely Not Pregnant
Most of us have thought it before: Why is my period late? Late periods are the worst! Having to constantly worry about when it will come, and if your bedsheets and underwear will get stained , is a huge bummer. More than that, for some sexually active people, having a late period can be one of life's most stressful experiences, and unprotected sex before a late period can mean it's time to take a pregnancy test. But if you're not sexually active, and you're sure you aren't pregnant, there are still plenty of reasons for a delayed period.
Has your teen started her periods but has some problems with irregularity? If your teen misses her period, it is natural to panic and assume the worst. But missing a period does not always signify a pregnancy.
