Or maybe your second period took you by surprise by coming much earlier than you expected. After all, periods are supposed to be predictable, aren't they? Is something wrong if they aren't? While there are women who get their periods every 28 days like clockwork, there's a wide range of what's normal.
And it's not at all unusual for a teen's periods to be irregular for the first few years of menstruation. The cycle for adolescent girls can be a bit longer—21 days to 45 days. If your periods are irregular, it may help put your mind at ease to first understand how the menstrual cycle works and why you even bleed in the first place. Every month your body goes through two main phases to complete the cycle and begin a new one.
The length of the menstrual cycle is measured from the first day of bleeding through the last day before your next period starts. Day 1 of the menstrual cycle is the first day you see any amount of bleeding. When a mature egg pops out of a Fallopian tube, it's called ovulation.
In the luteal phase, the uterine lining is made fully ready to nourish a fertilized egg if it implants. In other words, if you become pregnant. If that doesn't happen, the lining deteriorates and is shed. That's the blood you see when you have your period. The reason a teen girl's periods may not be following a predictable pattern is simply that the hormone axis between the brain and ovaries that controls ovulation is still developing.
After a year or two, when this hormone axis matures, periods should become more regular. Or at least they'll become more regular for you. If you think that might be the case, you should take an at-home pregnancy test. If your periods begin coming more than 35 days apart, or if you start having them really close together, there are lots of things that could be going on.
You could be stressed, exercising too much, have lost a lot of weight, or you may have some sort of hormone imbalance.

About the menstrual cycle
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.
Or maybe your second period took you by surprise by coming much earlier than you expected. After all, periods are supposed to be predictable, aren't they? Is something wrong if they aren't? While there are women who get their periods every 28 days like clockwork, there's a wide range of what's normal. And it's not at all unusual for a teen's periods to be irregular for the first few years of menstruation.
You are born with two small, grape-shaped ovaries inside of your belly on either side of your uterus. Ovaries are filled with hundreds of thousands of eggs. When you reach puberty and you are becoming a woman, your ovaries make hormones especially estrogen that cause breast development and menstrual periods. The egg then travels towards the uterus. If the egg is not fertilized by a sperm, then two weeks later, the blood filled lining of the uterus called the endometrium that becomes thicker between periods passes out of your body through your vagina. This flow, which comes out as blood, is your menstrual period. The whole process is called menstruation, and it will begin when your body is ready.
How Often Do You Get Your Period?
Menstruation is also known by the terms menses, menstrual period, cycle or period. The menstrual blood—which is partly blood and partly tissue from the inside of the uterus—flows from the uterus through the cervix and out of the body through the vagina. A menstrual cycle is considered to begin on the first day of a period. The average cycle is 28 days long; however, a cycle can range in length from 21 days to about 35 days. The steps in the menstrual cycle are triggered by the rise and fall of chemicals in the body called hormones.
