Puberty: What's happening to my body?

From around 10 years old your body will start to go through lots of changes as you are changing from a girl into a woman. This time is called puberty or adolescence. People sometimes say it is when you are “becoming a teenager”.

In girls, you may first see your breasts are growing. You may see hair between your legs and under your arms or you may suddenly get taller (a growth spurt).

No two girls are the same. If you develop earlier or later than other girls, it does not mean that something is wrong. Your body will develop when it’s ready.

Other changes you may notice:

  • Your hair is oilier now and needs washing more often.
  • You may start to get pimples on your skin.
  • Your body smell can change and you may sweat more.
  • Your breasts may feel sensitive or sore and begin to grow.
  • Your hips may get wider.
  • The hairs on your legs and arms may get thicker and darker.
  • You may notice a creamy coloured liquid (called discharge) from your vagina that leaves a stain on your panties.
  • You may even get your first period (this is when you start bleeding from your vagina once a month).

    The boys will start to change too! They may start later than girls. Boys’ voices may ‘crack’ or become deeper. Their muscles will get thicker and their shoulders wider. You may see hair start to appear on their faces.

    There is no way of telling when your menstruation is going to start. You must just be patient, it will come. Don't be scared

    My discharge is dirty and smelling i dont know why please help me when i go to clinic they gave me anti-biotic but still not clean

    Hi anonymous, A discharge which smells bad is usually treated with antibiotics. The clinic has a list of guidelines for which ones to use, and the same ones are recommended by all clinics, so it should have helped the discharge to get better. It is important to know that if this is a discharge caused by an STI (infection transmitted through sex) that if your partner doesn’t also take the antibiotics, you can get the same infection from them again. Both of you need to be treated at the same time to make sure you don’t keep passing the infection to each other. It is always important to use condoms, to prevent the discharge from coming back. You can use the Clinic Finder to find a clinic near you  here

    From last last month i started to get pimples on my face,i go to Doctor and give me Bco injection bt im worse nw,what must i do i dont like this pimples

    B-Wise Expert Expert 7 April 2018 19:48

    Hi anonymous, during our teenage years, we often get pimples, or acne, because of the increase in hormones that are coming into our body. It is important that you wash your face every morning and night, ideally with a cleansing soap – normal soap can dry your skin out which can sometimes make the acne worse. Speak to your nurse again about going onto an oral contraceptive as this can help with the hormones. Unfortunately, though acne is all part of growing up and there is no one way of getting rid of it all together.

    Hi anonymous, you do not say how old you are. Often when we are growing up we will have periods of weight loss due to various factors – one of which is that we are growing taller. During a growth spurt, it may be that we lose weight. Other factors also play a role in weight loss, such as stress. If you think back to that period, were you under a lot of stress? If you are continuing to lose weight, it may be a good idea to speak to the Doctor and see if there are any other symptoms that could be causing the weight to drop.

    Hi. Since I have given birth I've been having a problem of bleeding from my vagina, Nurses have prescribed contraceptive pills for me to use but yet the bleeding doesn't stop. it's been a year now. I really need help. I don't know what to do.

    Hi Anonymous, sorry to hear that you are going through this. Abnormal bleeding can happen if there is an issue with the female reproductive organs (such as the uterus or ovaries) or if there is an imbalance of hormones. The normal medication to treat abnormal bleeding is contraceptive pills or contraceptive injections and this treatment usually works to correct a hormonal imbalance, but it may not have worked. The first step is to return to the clinic or hospital for further investigation. A pelvic sonar will help to detect any issues in the reproductive organs. If nothing is found on the sonar, your doctor or nurse may prescribe other contraceptives to help with the problem.

    Do girls undergo Sam changes in voice sonding

    B-Wise Expert Expert 20 April 2018 15:10

    Hi Tomson. Girls' voices do also change, and become a little bit deeper during puberty. But, this is usually not nearly as noticible as the changes in boys' voices.
