When to test and what the results can mean

While headaches, nausea and a missed period can be signs of early pregnancy, the only way to confirm it is to take a home pregnancy test. Find out when and how to carry out the test for the most accurate result.

Am I pregnant?

Around six days after fertilisation, the cells that will become the placenta start producing a hormone called hCG (human chorionic gonadotrophin)1

After two weeks – probably around the time your period is due – the hCG levels should be high enough for a pregnancy test to detect it in your urine1.

When and how to take a test

The home pregnancy test you choose will have its own set of instructions, but many suggest doing it first thing in the morning – particularly if you’re testing early. If that’s not possible, try not to drink a lot beforehand as liquids may dilute your urine too much for an accurate result.

The tests are designed to detect raised hormone levels in your urine, so you will either need to dip the test stick in a sterile pot of your urine or place it in your flow. Either way, you’ll need to wait for what seems like a very long few minutes afterwards for the result.

Interpreting the result

Most home pregnancy tests can tell whether or not you’re pregnant on the first day of your missed period. But different brands show positive and negative results in different ways, so always read the instructions. Some will show a pink or blue line for positive, or a plus symbol. You can also buy digital tests which state ‘pregnant’ or ‘not pregnant’ in the test screen.

False negative result

There are several reasons why you may get a negative result. Firstly you might not be pregnant. Or you might not be making high enough levels of hCG for the test to detect it. This can happen if you test too early. So if you suspect you are pregnant, wait at least three days before testing again.

Next Steps

Home pregnancy tests are so accurate now that it isn’t usually necessary to have an hCG blood test at your doctors. However, if you are pregnant, you will need to inform your GP so that they can start planning your antenatal care.

Breastmilk is the ideal food for infants: it is best adapted to their specific needs. A healthy and balanced diet of the mother is important for the preparation and continuation of breastfeeding. Mixed breastfeeding can interfere with breastfeeding and reduce milk production. It’s hard to reverse the choice of not breastfeeding. If an infant formula is used for a non-breastfed baby, it is important to carefully observe the instructions for preparation and use and to follow the advice of the medical profession. Incorrect use could pose a risk to the child’s health. Socio-economic implications must be considered in the use of infant formula. After 6 months, in addition to breastmilk, water is the only essential drink. Do not hesitate to consult your health care professional if you need advice on feeding your baby.
