If you think you might be pregnant, you can take a pregnancy test to find out for sure. You can do this by seeing your doctor or buying a home pregnancy test kit from a pharmacy or supermarket.
Pregnancy tests check your urine or blood for a hormone called human chorionic gonadotropin (hCG). This hormone is made during pregnancy.
If you are pregnant, hCG increases quickly for the first 10 weeks of pregnancy.
hCG can be detected by a pregnancy test around 4 weeks after conception (when an egg is fertilised by sperm).
If hCG is found in your blood or urine, it is highly likely that you are pregnant.
Home pregnancy tests detect hCG in your urine.
There are different types of home pregnancy tests. You can buy these over-the-counter from a pharmacy or supermarket. Some digital kits are more accurate than traditional test kits.
There are 2 common methods for home pregnancy tests:
The dipstick tests for hCG use colours or symbols to show if you are pregnant. For example, they may show a pink or blue line, or a plus sign to show a pregnancy. Digital dipsticks may state the words ‘pregnant’ or ‘not pregnant’ and can be easier to read than symbols.
If you are trying to get pregnant, you can also buy ovulation tests at pharmacies. These tests predict when you are ovulating by measuring your hormones. Having sex in the days leading up to and the day of ovulation will give you the best chance of falling pregnant.
Most home pregnancy tests can detect hCG in your urine on the day your period is due. Some tests can detect hCG a few days before your period is due.
To get the most reliable results, wait until at least a week after your expected period before testing. By then, the amount of hCG should have increased in your body if you are pregnant.
Read the instructions carefully before doing a home pregnancy test. It’s best to collect your urine sample first thing in the morning, before drinking a lot of fluid.
If the test is negative but your period still doesn’t come, you could try re-testing in a few days. If the test is positive, it is most likely that you are pregnant. It is rare that you will get a positive result that is incorrect or false.
Nurses, doctors, or specialists can confirm a pregnancy with either urine or blood tests. The urine tests are similar to the home pregnancy tests.
The blood tests for pregnancy are more sensitive and accurate than urine tests. They can measure how much hCG there is in your body.
Your doctor can test your level of hCG. They may also test it again to monitor how quickly it is increasing. This is one way your doctor can tell if your pregnancy is normal. For example, an extremely high hCG level may be a sign you are going to have twins. It can also be a sign of some complications.
Always see your doctor if your home pregnancy test shows you are pregnant.

Your doctor may also recommend some tests, such as an ultrasound scan.
If your pregnancy was unplanned and you’re not sure what to do, it’s best to take some time to think about your decision. Your doctor can help you work through the options.

Getting a negative pregnancy test when you are trying to fall pregnant can be difficult for you, your partner, and your relationship.
At the same time, getting a positive pregnancy test when you were not planning on becoming pregnant can be difficult. It can help to talk to people close to you or a professional counsellor.
