Pregnancy

How does pregnancy happen?

Pregnancy (conception) occurs when a sperm fertilises an egg by joining with it during, or shortly after, sexual intercourse. If a woman does not want to become pregnant when she has sex she and/or her partner can use contraception.

Women can get pregnant at any point in their menstrual cycle, but this is most likely to happen around ovulation (when the egg is released from a woman's ovaries). This happens around day 14 of the cycle (day 1 is the first day of your period), but it is very difficult to know exactly which are the fertile days of the cycle.

Once the egg has been fertilised it moves into the womb where it can start to grow into a baby.  The woman will then miss her period or have a lighter or shorter period than normal.

If the egg starts to grow but does not develop properly the pregnancy can end in the early stages and this is called a miscarriage.  The woman may experience period pain and bleeding.

If you do not wish to become pregnant you can use Emergency Contraception up to 5 days after having unprotected sex.

Can I become pregnant as a result of oral sex?

No, a woman cannot become pregnant as a result of oral sex. Pregnancy can only occur if sperm is introduced into the vagina.

How do I know if I am pregnant?

Any woman who has unprotected sex (without contraception) can become pregnant – even if it is the first time. For more information on contraception please click here.

If you are pregnant, you might not feel any different from normal. Often, the first and most reliable sign of pregnancy is a missed period, or for a few women, a shorter or lighter period than usual.

Symptoms:

Some women do get symptoms, but not usually until a few weeks after conception (when the egg and sperm first meet). These may include:

  • Swelling or tenderness of the breasts
  • Feeling sick (often called morning sickness, although not always occurring in the morning)
  • Frequent need to wee
  • Feeling tired
  • Changes in appetite or going off certain foods

There is only one way to know for sure and that is by taking a pregnancy test

When should I take a pregnancy test?

Most pregnancy tests work as soon as a period is late (so if your period was due Monday the 24th you could take the test from the Tuesday 25th). But, while most women do not continue to have periods when pregnant, a few may experience some light bleeding. And for women who do not have a regular cycle it can be difficult to know when a period is due. So, the best time to take the test is three weeks after having unprotected sex - this is roughly how long it will take for markers of pregnancy to show up on the test. 

What should I do if the pregnancy test is negative?

If the test is negative, this probably means you are not pregnant, but if your period still hasn't arrived a week later, another test should be taken. Periods can be late for many reasons including stress, change of diet, or other health conditions. If you are concerned, then make an appointment to see your GP.

If you are not planning to become pregnant this might be a good time to think about finding a method of contraception that suits you best. If you have questions about contraception you should make an appointment with your GP, nurse or health advisor.

What should I do if the pregnancy test is positive?

If the test is positive this means you are pregnant.

Finding out that you are pregnant may give rise to very different feelings for different people. Some people may feel excited and happy; others may feel scared and confused. All of these feelings are normal.

If you are planning to continue the pregnancy you need to see your GP to discuss the care that you will need during the pregnancy and birth.

If you are unsure about whether to continue you should seek medical help as soon as possible – from your GP, a family planning clinic or a sexual health service so that you can discuss your options.  The staff will be used to helping people in this situation and will be able to give you the information that you need to make your decision.

I think I might be pregnant and am getting some pain and bleeding

Sometimes in early pregnancy it is not clear whether the pregnancy is developing normally.   The signs of this are bleeding and abdominal pain.  If you experience this you need to be referred to an Early Pregnancy Assessment Unit for tests (usually a scan and/or blood tests).  You can be referred by your GP, sexual health clinic or a hospital casualty department.

Sometimes these tests will show that the pregnancy is not able to develop (a miscarriage) or has developed in the tube instead of the womb (ectopic pregnancy) and you will be given treatment and advice.  An ectopic pregnancy can be dangerous so if you do get these symptoms it is very important to see a doctor as soon as possible.

My girlfriend is pregnant, what should I do?

Discovering that your girlfriend is pregnant can often come as a shock. You'll probably have lots of questions and want to know what your options are. It's a good idea to talk about your thoughts and feelings with your girlfriend, friends or family, or you can get some advice from a health professional.

If you're under 18, the Sexwise confidential helpline is available from 7am until midnight, 7 days a week. Calls from a landline are free, and they won't show up on a telephone bill. The number is 0800 28 29 30. 

What choices do I have if I am pregnant?

If you are pregnant there are three choices available to you:

The decision about what to do can be a very difficult one, especially if the pregnancy was unplanned. You may need to consider your age, relationship with the father, family, financial situation, housing, and cultural factors amongst others. You can get advice and support with decision making from sexual health clinics or your GP, as well as friends and family.

Where can I get a test?

If you have missed a period or suspect that you might be pregnant, you will need to take a pregnancy test. A pregnancy test can be carried out from the first day of a missed period using a sample of urine. 

You can get a pregnancy test done for free at:

  • community sexual health clinics
  • sexual health clinics in your local hospital
  • young people's clinics
  • your General Practice

Alternatively you can buy a pregnancy testing kit to use at home from the pharmacy or supermarket. These usually cost about £10. 

If you're doing the test yourself remember to follow the instructions carefully - if you don't it could affect the results.
