This means there are 28 days between the start of your last period and the start of your next period. Cycles can be longer or shorter than this. During puberty, reproductive organs begin to develop. When people with a uterus are born, there are hundreds of thousands of eggs ova inside their ovaries. This process is called ovulation. The egg moves along the fallopian tube towards the uterus.
At the same time, the lining of the uterus becomes thick and soft with blood and tissue. This happens just in case the egg is fertilised. It would then implant itself into the lining of the uterus and grow. Fertilisation only happens if the egg joins with a sperm. When the egg is not fertilised, the lining of the uterus is not needed so it comes away and is released through your body through your vagina.

All these hormones work together to start the changes in puberty. When does puberty start? What are the hormones?
People with a vagina During puberty your ovaries get bigger and your body will start to produce two hormones — oestrogen and progesterone. The process can take up to 4 years.
Children who begin puberty either very early before the age of 8 or very late after 14 should see a doctor just to make sure they're in good health. It's normal for breast buds to sometimes be very tender or for one breast to start to develop several months before the other one. Puberty can be a difficult time for children. They're coping with changes in their body, and possibly acne or body odour as well, at a time when they feel self-conscious.
But the "emotional rollercoaster" they're on can have psychological and emotional effects, such as:. Find out more about teen aggression , coping with your teenager and talking to your teen.

All of these changes mean that their bodies are developing as they should during puberty. Girls' bodies usually become curvier. Their hips get wider and their breasts develop, starting with just a little swelling under the nipples.
Sometimes one breast grows more quickly than the other, but most of the time they even out. Girls may start wearing bras around this time, especially if they are involved in sports or exercise classes. With all this growing and developing going on, some girls may be uncomfortable with how their bodies are changing, but it's unhealthy for girls to diet to try to stop any normal weight gain.
If you have any questions about puberty or are worried about your weight, talk to your parent or doctor. One question a girl will have is: When will I get my first period? This usually happens about 2 years after her breasts start to develop. The menstrual say: MEN-strul period , or monthly cycle, is when blood is released through the vagina.
That may sound alarming, but it's normal and it signals that a girl is growing up and her body is preparing so that she can have a baby someday. Here's what's going on: Each of a girl's two ovaries holds thousands of eggs. During the menstrual cycle, an egg is released from one of the ovaries and begins a trip down the fallopian say: fuh- lo -pee-un tube to the uterus, also called the womb.
A girl has two fallopian tubes, one connecting each ovary to the uterus. Before the egg even leaves the ovary, though, hormones stimulate the uterus to build up its inner lining with extra blood and tissue. If the egg gets to the uterus and is fertilized by a sperm cell, it may plant itself in that lining and grow into a baby. The extra blood and tissue nourishes and protects the baby as it develops.
But most of the time the egg is only passing through. When the egg doesn't get fertilized, or if the fertilized egg doesn't become planted in the lining, the uterus no longer needs the extra blood and tissue, so the blood leaves the body through the vagina. This blood is known as a girl's period. A period usually lasts from 2 to 7 days.
About 2 weeks after the last period, a new egg is released as the cycle repeats itself. Another thing that may come with puberty is acne say: AK-nee — or pimples — caused by all those hormones at work in the body. Skin gets oilier and pimples sometimes start showing up when puberty begins, and you may get them throughout the teenage years.
You might see pimples on your face, your upper back, or your upper chest. To help control pimples, wash your face twice a day with warm water and a mild soap or cleanser. Don't squeeze, pick, or pop your pimples.
Your doctor can also offer suggestions for clearing up acne. The good news is that acne usually gets a lot better as you get older. A lot of kids notice that they have a new smell under their arms and in other places when they hit puberty — and it's not a pretty one.
How your child manages puberty emotionally might also be affected by additional needs. A health professional can answer any questions you have about this. Your GP or other health professionals working with your child can help.
