What is happening to my body?

Have you wondered why you suddenly feel so DIFFERENT?

Maybe you have been wondering for a while or maybe you just woke up one day and thought that nothing is the same anymore. In God’s Word we learn that even the smallest thing was important to Him when He made you, perfectly. So, for that reason all of these changes are normal and should be so! Read Psalm 139 verses 13 and 14.

What changes happens in girls’ bodies?

  • Body fat increases
  • Breasts start to develop
  •  Armpit- and pubic hair starts to grow
  •  Hips become wider
  • Hair and skin becomes more oily
  •  Height and weight increases
  •  Start to menstruate
  •  Pimples can start to appear
  •  Breasts start to develop


A girl’s first period is more or less the same time as when her mother’s first period was.

The first sign of puberty for girls is the development of breasts. This happens when girls are more or less 10 years old. The one breast usually starts to develop before the other and is usually on the side of your writing hand. The cervix also releases a creamy, sometimes slimy liquid which is meant to keep the vagina moist, clean and free of germs. Sometimes girls’ panties can become wet from this. It is normal! Girls’ ovaries receive the signal to start making estrogen. Estrogen helps girls’ bodies to become mature. It works with the womb and eggs and all has to do with becoming pregnant one day. Every 28 days, an egg is released by one of the ovaries. A girl already has all of her eggs at birth.

What changes happens in boys’ bodies?

  • Muscles start to develop
  • Height and weight increases
  • Armpit-, facial hair and pubic hair starts to grow
  • Testicles start to grow and become bigger
  • Scrotum becomes darker
  • Penis grows longer
  • Voice breaks and becomes deeper
  • Pimples can start to appear
  • Skin and hair becomes oily
  • “Wet dreams” can happen


Boys start to get an erection. This can happen when they think about sexual things or even for no specific reason. Boys can also get an erection when they are sleeping and then ejaculate. That means that semen can come out of the penis and this is then called a “wet dream”.

All of these changes happen when certain hormones are released by your brain, giving your testes the signal that
the sperm and testosterone must be made. Testosterone is the hormone which causes all of the changes. Sperm
cells are necessary when a man and woman want to have children.

Good. Let us start at the beginning!

You have probably heard adults talk about puberty {pew-bur-tee}. It is a clever word that they use to describe
the time in your life when your body starts to change.


The development of boys and girls is different and does not start at the same time?

Puberty usually starts between the ages of 7 and 13 for girls and 9 and 15 for boys. Every person’s development is different, but ultimately everyone will go through the same changes. This is what makes us all so special – each of us has unique characteristics, inside and out! The changes which are happening in your body are normal and a part of becoming an adult. When your body reaches a certain age, puberty, the brain releases special hormones which cause all of the changes. These hormones do not only cause changes in your body but can also make you feel strange and have confusing emotions. It is important to know about all of the changes before they happen and to remember that it happens to everyone!

The egg moves slowly through the fallopian tubes into the womb and can stay alive there for 24 hours.
The womb has prepared in advance to be able to keep the egg there and let it grow by thickening and collecting blood in the wall. If the egg is not fertilised by the sperm cell of a man, it dies and is expelled. This happens when you menstruate. You may also have heard that some girls talk about their “periods”. It is not the same for all girls and
when you start menstruating it can happen that you skip some months. This is because the cycle is very topsy-turvy at the beginning, but it will become more regular within two years.


The same hormones that cause pimples are the hormones which make your hair extra oily. Your sweat glands, which have behaved well up until this point, are now working way too much and suddenly you are sweating more and it has a stronger scent. With all the changes it is important that you wash regularly with soap and warm water. Clean clothes and deodorant will help you to smell nice and fresh! Boys’ facial hair is also growing fast now. The facial hair of guys with darker hair will become visible quicker than guys with lighter hair. Shaving is a big step in a boy’s life!


You may feel like you want to explode with happiness one day, just to find that you feel like nobody understands you the following day. This is also normal and everything thanks to the big changes which are taking place in your body. The best thing you can do is to pluck up the courage to tell someone about it.

Who can you talk to about this?

  • Your parents
  • A good friend
  • A teacher whom you trust
  • A professional person such as a social worker or counsellor
  • Someone at your church whom you trust


You can also talk to God and tell Him anything that bothers you. Ps. 55:22, “Cast your cares on the Lord and he will sustain you; he will never let the righteous be shaken.”

You can also phone Childline. There are people who would love to listen to you. Phone them at 0800 055 555.
