Becoming a woman
A rite of passage
Becoming a woman is a rite of passage that starts with the changes of early puberty and ends with a woman's first periods. Many cultures have rituals to celebrate this process. Apache Native Americans celebrate for several days to mark the transition from girl to woman.
Several issues are important to girls who are becoming women. These include:
puberty
the menstrual cycle and periods
pregnancy and contraception
breasts
vaginal discharge
sexually transmitted infections.
Puberty
When should puberty start? Puberty in girls usually starts at any time between 8 and 13 years of age, periods usually start about two years after the start of puberty.
What happens during puberty?
A girl grows and changes in ways that prepare her to be able to have a baby. These changes occur in certain stages.
First, girls can expect to develop breasts. These start from a small and often painful lump or 'bud' underneath the nipple. Breasts can take five years to reach their final size and shape. So girls, don't worry if your breasts do not currently match your idol from Baywatch.
Hair starts to grow under the arm and in the pubic (genital) area.
The explosive growth spurt: this is greater than any other time except the first year of life.
The body shape becomes curvier. During this time it is normal to put on weight, especially at the hips and stomach (puppy fat as it's rather insultingly called!) so don't go on a starvation diet.
The body odour can change especially under the arms, and you notice increased perspiration.
Some people get acne on the face and back.
Vaginal discharge starts or changes.
Teenagers experience a change in their emotions and new sexual feelings.
Periods start.
Why do these changes occur?
Natural chemicals that circulate in the body, called sex hormones, cause these changes. At the start of puberty, the brain releases a hormone known as gonadotrophin-releasing hormone (GnRH). This causes the release of two more hormones called follicle stimulating hormone (FSH) and luteinising hormone (LH) into the bloodstream. LH and FSH in turn stimulate the ovaries, which contain your eggs, to release the hormone oestrogen that leads to the changes girls go through during puberty.
The menstrual cycle and periods
What is a period? A period is the vaginal bleeding that women usually experience at regular intervals of about a month from puberty to menopause (the end of periods that, on average, occurs in your early 50s). Periods are also called menstruation.
Why do women have periods?
Periods are a part of the menstrual cycle that happens roughly every month to prepare a woman's body to have a baby.
Every woman has thousands of eggs in her ovaries. Once a month or so, one of these eggs matures and travels into the Fallopian tubes. These tubes propel the egg along towards the uterus (the womb), in the hope of meeting a sperm and becoming fertilized to become an embryo. If fertilized, the egg then continues its way along the tube and becomes implanted (embedded) in the uterus where it develops into a foetus. In this way, the woman becomes pregnant.
While the egg is on its travels, the uterus is being prepared for the implantation of the embryo. Its lining builds up to become cushion-like and engorged with blood. If the egg is not fertilized, the womb sheds this blood-filled lining, and this bleeding is what we call a period.
The cycle then repeats every month or so unless the woman becomes pregnant.
What controls the menstrual cycle?
Again, hormones control the process. The menstrual cycle can be split into four stages.
Menstrual (bleeding) phase: all the hormones are at their lowest level and consequently the womb sheds its lining and the woman has her period.
Pre-ovulatory phase: the ovary starts to secrete oestrogen, which leads to a gradual build up of the uterus lining in preparation for ovulation.
Ovulation: at a critical point roughly 14 days after the start of bleeding, the level of oestrogen reaches such a height that it causes the brain to release a large amount of LH, which in turn stimulates release of an egg from the ovaries.
Post-ovulatory phase: after the release of the egg, the ovaries produce another hormone, progesterone, which maintains the lining of the womb so a fertilized egg can implant. If the egg is not fertilised, progesterone and oestrogen levels drop, the womb loses its lining, and, about 14 days after ovulation, the menstrual phase begins again.
What is the menstrual cycle like?
The average cycle is 28 days although it can be as short as 21, and as long as 35 days.
Menstrual phase: day one of the menstrual cycle is the first day of bleeding, which can last anything from a couple of days to a week. The bleeding is heaviest on the first few days. Women use tampons that sit inside the vagina or sanitary towels (pads) outside the vagina to soak up the blood. Many women suffer from cramp-like abdominal pains. Occasionally, they also have back pain. The pain is caused by changes in local hormones called prostaglandins.
Pre-ovulatory phase: many women feel very well during this phase, probably due to the rising levels of oestrogen.
Ovulation: your vaginal discharge can increase and become mucus-like, which is more welcoming for sperm. At ovulation, the body temperature rises. Some women may experience sharp pain on either side of the lower abdomen. Occasionally, a few spots of blood come from the womb.
Post-ovulatory phase: symptoms of the premenstrual syndrome occur in this phase as the hormone levels fall. When the hormones are at their lowest, just before the menstrual bleeding starts, women who are more sensitive to the changing hormone levels can experience depression, irritability, lack of concentration, tiredness, food cravings, bloating and sore, tender breasts.
What if I don't have a period by age 14?
Some girls do not get their periods until they are 16. The age of getting your period can run in the family so ask your mum and your gran when they started theirs. If you are over 16 and still have no period, you may be perfectly healthy but you should check with your GP (family doctor). Some things can delay your period:
being underweight or very overweight
too much exercise
stress
illness
pregnancy.
What causes irregular periods?
When you first start having periods, it is normal for them to be irregular. It usually takes two years for them to become regular and for some people it is much longer. This is because at the beginning the time to ovulation (pre-ovulatory phase) varies and sometimes you might not ovulate at all.
What happens if I stop having my period?
If you have had unprotected sex then you need to have a pregnancy test to check whether you are pregnant. You can go to your nearest family planning clinic (FPC), sexual health clinic (also known as a sexually transmitted disease or genitourinary medicine clinic), your GP, or you can buy them over the counter at the chemist.
Other reasons can be losing too much weight, too much exercise, or stress. If the problem continues you should go to see your GP.
Will tampons make me lose my virginity?
Loss of virginity is when you first have sex. There is a thin membrane inside your vagina called a hymen, which tears and sometimes bleeds the first time you have sex. The hymen is usually very elastic and tampons can be inserted without tearing the hymen. However, even if using a tampon tears the hymen, this does not count as a loss of virginity as no sex is involved. Rarely, the hymen can tear when bicycle riding, horse riding or climbing fences but this does not mean you have lost your virginity.
Can tampons get lost inside me?
No. Tampons lie in the vagina. The neck of the womb (cervix) lies at the top of the vagina and it is tightly closed except for a tiny hole about the size of a pinhead. A tampon cannot move into the womb and has no other way out except the way it went in. Sometimes a tampon can be at the top of the vagina behind the cervix and then it can be difficult to feel or pull out. If you suspect that you have left a tampon in, especially if you notice an unpleasant smelling discharge, then go to your GP or sexual health clinic to have it removed without delay.
Can I swim or have sex during my period?
Yes. You should be able to have a completely normal life during your period. Remember that you can get pregnant if you have unprotected sex during your period.
Is period blood dirty?
No. It is just normal blood mixed with the lining of your uterus. If it were dirty then it would not be a suitable place for the baby to develop. Once the blood leaves the womb it can become food for bacteria so you need to change tampons and sanitary towels regularly and discard them in a suitable waste disposal place.
I feel terrible before my periods, what can I do?
Feeling emotional, irritable, tearful, tired and bloated before a period are all the symptoms of premenstrual syndrome (PMS). Many women have this condition and sometimes just knowing about it and predicting when it will happen is enough to help you through it. Things that help lessen symptoms include:
exercise
eating fresh food
avoid processed food
avoid too much salt eg crisps
avoid caffeine (remember that chocolate and cola also contain caffeine)
eat regular small meals
pamper yourself
Evening primrose oil and/or vitamin B6 supplements sometimes help (note: controversy exists over whether high doses of vitamin B6 can cause nerve damage).
If PMS is very severe, go to see your doctor. Some women choose to go on the contraceptive pill (the Pill) to control the hormonal swings that prompt PMS.
My periods are so painful, what can I do?
Gentle exercise can make you feel better, (though heavy exercise can make things worse). Getting regular exercise between periods can also help.
Hot baths relax the muscles and can reduce the severity of the pain.
Over-the-counter painkillers called non-steroidal anti-inflammatory drugs (such as ibuprofen) can help reduce the pain if taken regularly in the first few days of the period.
If all this fails go to see your doctor. Some women go on the Pill to control severe period pains and your doctor can also prescribe alternative painkillers, such as mefenamic acid.
Pregnancy and contraception
How do women become pregnant?
A woman becomes pregnant if the egg released at ovulation is fertilized by a man's sperm and then travels along the Fallopian tube to implant in the prepared womb.
Once released, the egg can survive for between 24 and 48 hours and will be discarded if it is not fertilized in that time.
During unprotected sex (without using contraception), the man deposits hundreds of thousands of sperm in his semen at the top of the vagina. The sperm are very resilient in their long swim from the vagina through the cervix, into the uterus and up the tubes. They can survive for up to seven days waiting for an egg.
Contraception
If you choose to have sex, remember the risks of pregnancy and infection. Condoms can protect against pregnancy and sexually transmitted infections, although they are not as reliable in preventing pregnancy as some other forms of contraception. For further protection against pregnancy, go to your GP, FPC or sexual health clinic and get contraceptive advice. Although no form of contraception is 100 per cent effective (except abstinence!), there are plenty of safe and easy ways to protect against pregnancy. The doctors and nurses can help you find one that is suitable for you.
Good advice
Always carry a condom if you are considering having sex: you cannot rely on the other person to think about your health and wellbeing.
Can I become pregnant if I have sex during my period?
Yes it is possible. You cannot predict the exact time of your ovulation and it could happen that in any particular cycle you ovulate earlier than usual. As the sperm can survive up to one week, the egg can be fertilized and you will be pregnant. For example, if you have sex on the fourth day of your period, and you happen to ovulate seven days later on the 11th day of your cycle, some sperm might still be around to fertilise your egg and you will fall pregnant.
Is there a safe time I can have unprotected sex and not get pregnant?
Firstly, you should remember that using a condom protects not only against pregnancy but also sexually transmitted infections. Unprotected sex is never 'safe'.
The time when sex is very unlikely to get you pregnant occurs during the post-ovulatory period (more than two days after ovulation until the arrival of the next period). So if you have an extremely regular 28-day cycle, days 17 to 28 are likely to be safe, but if you happen to be even one day late with ovulation then day 17 would not be safe. This can happen because the time of ovulation can vary cycle to cycle (more so if your cycle is not regular). You can buy a kit from the pharmacy that detects exactly when your ovulation occurs, although this form of contraception is not as reliable as some others.
My boyfriend pulls out before he comes, can I become pregnant?
Unfortunately, pulling out or withdrawal is not reliable for contraception because men release something called pre-come or pre-ejaculate before they ejaculate which they do not notice. This tiny amount of fluid that comes from the penis contains thousands of sperm that can fertilize your eggs. Remember that during the teenage years and early 20s women are at their most fertile, and it takes only one sperm and one egg to make a baby.
I always wash inside my vagina after sex, will that protect me against pregnancy?
No, sperm are very agile and they reach the neck of the womb in a matter of seconds. Even the fastest sprinter could not beat them to the bathroom. In addition, the womb contracts to suck the sperm in.
What if a condom breaks?
Condoms should rarely break if they are used properly, and before their expiry date. Make sure you know how to put on a condom properly.
Within 72 hours: Go to your nearest family planning or sexual health clinic and get emergency contraception (usually the 'morning after' pill). On a weekend, many casualty departments supply emergency contraception. You should also be able to obtain emergency contraception if necessary from the out-of-hours GP service. You can also buy the emergency contraceptive Levonelle from pharmacies if you are over 16.
The earlier you take emergency contraception the more effective it is.
Although there is a very small chance that you may be come pregnant even if you take it within the first 24 hours, the risk of pregnancy increases the longer you leave it and 72 hours is the limit.
The morning after pill is a large dose of hormones:
either a progesterone-like hormone called a progestogen (brand name Levonelle or Levonelle 2).
or a combination of a progestogen and oestrogen (Schering PC4).
Beyond 72 hours: you can still go to a family planning clinic, as the doctor might be able to insert an intrauterine device (a coil) into the womb to prevent the fertilized egg from implanting.
Can I become pregnant from sperm left in the bath or swimming pool?
No. This is a myth.
How do I know if I am pregnant?
If you have had sex without using any contraception since your last period started, and your next period does not come when it should you might be pregnant.
On the day that your period should have arrived and didn't, you can test if you are pregnant using a pregnancy test. You can buy these at the chemist or you can get one free at a FPC or sexual health clinic or your GP. The test is simple and is done on your urine sample. Do not use an out-of-date test, and follow the instructions carefully. If the test is negative and your period arrives soon after, fine, but otherwise always confirm the results with a doctor.
What can I do if I am pregnant?
You should contact your doctor, a FPC, a sexual health clinic or Brook Advisory Centre. The staff can explain your options and help you to choose. It is advisable to involve your parents in any decisions you make.
Breasts
At what age do breasts normally develop? Most girls start to develop breasts between the ages of 8 and 14. For many, this is one of the first signs of becoming a woman.
Is it normal to have different sized breasts?
Yes 40 per cent of women have different sized breasts.
Do sore breasts mean breast cancer?
It is extremely rare to develop breast cancer during puberty and breast cancer is very rarely sore. Growing breasts can be very sore. Later on, the breasts can become sore during the fluid retention before the period. Sometimes reducing the salt and caffeine in your diet can help.
Pregnant women also develop sore breasts, which can be one of the first signs of pregnancy. So if you've missed a period and have sore breasts, do a pregnancy test.
Vaginal discharge
Another thing that changes during puberty is that vaginal discharge (secretions) start or change. For six months before getting their first period, girls may notice an increase in vaginal discharge.
What is normal vaginal discharge? Vaginal secretions keep the vagina moist and clean and help fight infections. Once periods start, normal vaginal discharge can be thin, sticky and elastic; or thick and gooey, and the colour is clear, white or off-white (yellow when dried). The texture and colour can change throughout the cycle. In particular, some women notice a heavier flow of thin, sticky mucus-like discharge around the time of ovulation (day 14 of the cycle). Normal vaginal discharge usually has no smell, and if it has, it is not unpleasant. Remember, if you are sexually excited or emotionally stressed your vaginal discharge can increase.
