Some pregnancy tests are designed to detect pregnancy before your period is meant to start. However, others will only provide you with an accurate result after you have missed your period. It's important to check which type of pregnancy tests you are buying so you know when the right time to take the test will be. Scroll down to see more on how soon you can do a pregnancy test and how accurate pregnancy tests are, as well as everything you need to know about taking a pregnancy test.
How we tested these pregnancy tests
Choosing a pregnancy test from the hundreds available can be daunting, especially when you want to have confidence in the results. When testing and comparing, we kept in mind how easy the test was to read and use, as well as some of the factors below, such as value for money and how quickly it can accurately detect hCG.
To help you decide which is best for you, there are a few factors to consider when you’re choosing the best pregnancy test:
Price: There’s a wide variety of tests out there, ranging from a few pounds to over £10. The more expensive ones come with clearer digital displays and may show you how far along your pregnancy is. Some people like this extra information, while others simply want to see a positive or negative result and have further information confirmed at their first ultrasound.
Sensitivity: Pregnancy tests work by testing for the hormone human chorionic gonadotrophin (hCG), which starts to be produced around 6 days after fertilisation. If you have a 28-day cycle, you should be able to detect hCG in your urine 12-15 days after ovulation. Most pregnancy tests can detect hCG levels from 25 mIU/ml, though some of the more sensitive early tests can detect hCG levels as low as 10 mIU/ml.
Date tests: Some tests will show you how many weeks pregnant you are, up to 3+ weeks. This can be helpful in allowing you to know when you might have conceived and a rough idea of the due date. This is something you’ll discover at your first ultrasound, but as this is normally around 12 weeks some people prefer to find out sooner.
Display: Some pregnancy tests show whether you’re pregnant with two lines or a plus sign. This could be in blue or pink dye. Other tests with digital displays will show the word "Pregnant" or "Not Pregnant," which many people prefer as a clear yes or no.
The best pregnancy tests in the UK 2024:
Best pregnancy test overall
Clearblue is one of the most well-known pregnancy test brands and is the one most recommended by doctors in the UK. This particular Clearblue test has two tests for added reassurance and accuracy so you can double-check the result. One review pointed out that it also makes it “value for money, 2 for the price of one”. Both are packed with features, including a digital display that leaves no room for doubt, showing either Pregnant or Not Pregnant. The digital display makes it much easier to read than some linear pregnancy tests, with one review saying that it’s “easy to use and much more precise than the line pregnancy tests”.
It can also detect pregnancy earlier than your missed period, meaning less waiting, and you also get to find out how many weeks pregnant you are. Clearblue claims this test is as accurate as an ultrasound scan at dating your pregnancy, and reviewers agreed, with one saying it “works well and is very accurate. The accuracy of the weeks was confirmed for me by the hospital when I had to have an early scan”. While reviewers found it to be accurate within the first 3 weeks of pregnancy, some pointed out that anything over three weeks will just show as 3+ weeks.
The Clearblue rapid result pregnancy test turns pick when urinated on, but this dating test doesn't turn pink and is a little narrower area to aim for, so you may find it easier to pee into something and pop the tip of the stick in.
Pros
- The display shows the number of weeks so it's clearer and gives an idea of the dates
- Can use them to test early
- Two tests in one box offer a chance to reconfirm results
- Users felt the dating was accurate
Cons
- Anything over three weeks will just show as 3+ weeks

Best pregnancy test for multiple testings
Along with Clearblue, First Response is a brand you will likely spot on the shelves. This is another that comes with a well-earned reputation for accuracy and we particularly like the Triple Check Pregnancy Test. The package comes with three different tests, in colour-coded packaging – the first is a First Response, which detects the pregnancy hormone from the day of your expected period. It claims to be 99% accurate, and one reviewer felt it was “honestly the best tests on the market for early, accurate results. Picked up my pregnancy at 3 weeks and 4 days!”
The second and third tests are a Digital pregnancy test with a Yes or No answer and a Rapid Results test, which will give you an answer in one minute on the day of your missed period. While reviewers rated the early detection tests, feedback was mixed on the digital test, with a number feeling that this was inaccurate compared to other tests.
If you like the reassurance of being able to do multiple tests, this could be a good pregnancy test to purchase. Rather than a cross result coming up in the window, it gives two lines, which some may find a bit harder to read. With any pregnancy test, always be sure to keep the instructions so you can interpret your results correctly.
Pros
- Over 99 per cent accurate to offer confidence with early testing
- Three tests in one box offering a chance to test at different stages
- Easy to use with clear colour coded-packaging for the three-step test
Cons
- Some users say that the digital one may be inaccurate
| Number of tests: | 3 |
| Display Method: | Both lines and digital |

Best pregnancy test for early detection
While the most important part of a pregnancy test is the positive or negative result, it’s very exciting to know how far along your pregnancy might be so you can start thinking about that all-important due date. The Clearblue Pregnancy Test Ultra Early Triple-Check and Date Combo Pack not only gives you an idea of how many weeks pregnant you are (up to 3 weeks+), but it can also give you results up to six days before your missed period. This is a whole day earlier than many other tests, so it's great for those who just can't wait to find out.
Reviewers liked that the pack includes three tests - with two Ultra Early Pregnancy Tests and one Pregnancy test with Weeks Indicator - and felt it “offers great value, exceptional sensitivity, and unsurpassed user-friendliness, making it an invaluable tool for those early days of pregnancy”. They appreciated the “blend of both the traditional and digital aspects of pregnancy tests that provides the assurance one needs during such a critical period”.
Since early testing isn't as accurate as testing on the day of your period, as it depends on your hCG levels, having two tests, plus the dates indicator, means that you can test again closer to your period if you do get a negative result. Then, once you get the positive result, you can check how many weeks, which is another exciting bit of information to be able to get.
Pros
- Can test 6 days before the expected start date of your period
- Contains three tests for early detection and dating your pregnancy
- Two traditional tests and a digital test offer the best of both worlds
Cons
- Some reviewers found the blue lines harder to distinguish if faint, compared to other tests which have pink lines

| Display Method: | Line and digital |
| Results Time: | 3 minutes |

Best ovulation and pregnancy test
If you’re trying to get pregnant, you might want to consider investing in this ovulation and pregnancy test. With 10 fertility tests, it’s easy to pinpoint the best time to get pregnant. The tests track a fertility hormone, luteinising hormone (LH), which increases 24-36 hours before ovulation, giving you a window of ovulation. This is a more accurate way of testing than using the basal body temperature (BBT). Reviewers appreciated how easy it was to use with one saying it was “much easier to understand than a typical low price ovulation test. No ambiguity on determining if a line is positive or negative, the smiley face does the job for you”.
While they are more expensive than some own-brand tests, reviewers had great confidence in Clearblue, with one saying, “These may be expensive, but both times I have used them they have accurately picked up my ovulation and helped me to conceive”.
One Clearblue Rapid Detection Pregnancy Test is included and can give a result in just one minute when used from the date of your expected period. However, we know from our mum testers and reviewers that they feel more confident doing multiple tests, so you might want to buy another test from our round-up of the best pregnancy tests.
There are 10 ovulation tests included, which is plenty for at least two cycles. By then, if your period is quite regular, you should be able to pinpoint your ovulation window accurately, even without the tests. If your period is irregular, using these tests is a great help.
Pros
- Can be used to predict your ovulation date, improving your chances of getting pregnant
- Ten ovulation tests are included to allow you to do multiple tests around your suspected ovulation date
- The easy-to-read 'smiley face' lets you know if it's the right time
- Tests the luteinising hormone, which is a more accurate way to predict ovulation
Cons
- Only includes one pregnancy test

Best multipack pregnancy tests
While these tests mean you may be getting up close and personal with your urine; we’d say it’s a small price to pay for a multipack of 20 strips. Simply immerse the strip into a sample of urine, take the strip out after three seconds and lay it flat, checking the results after three minutes. One reviewer said, “These are the cheapest and most reliable pregnancy tests you can get. You dip them in a pot rather than hold them in the urine stream. They are quite fast working”.
These tests are very sensitive and can detect pregnancy before your period is due, though the lines may be faint in the early pregnancy stages. Reviewers appreciated the confidence it provided to be able to take multiple tests to confirm results, with one using them over many days and saying, “I started getting faint positives and can see the line progression well. I have tested loads with these over the last few days and can see darker lines today”.
While you do get 20 test strips, the kit doesn't come with a plastic pot for urine—which some other tests do. This means you have to find a plastic cup or something similar, but for the value for money, we still think this product is worth it, especially if you're hoping to pick up your pregnancy earlier or want to do multiple tests.
Pros
- Large multipack for multiple testing
- Only needs dipping in urine for 3 seconds and can be read in 1 minute
- Multiple tests can give confidence in the results
Cons
- Doesn't come with a container for urine
| Number of tests: | 20 |
| Display Method: | Line |
| Results Time: | 3 minutes |
| Sensitivity: | 10mIU/ml |
Best pregnancy test for accuracy
This Accufast pregnancy Test claims to be 99.99% accurate, so should provide peace of mind to prospective parents. It offers the option of using it as either an in-flow test - where you hold it in your urine stream for about 5 seconds - or using the cup which is provided to collect urine and dip the test in. You then lay it flat, and your results should arrive in 3-5 minutes. Reviewers thought it was accurate, with one saying, "This was a middle of the afternoon wee as I couldn't wait, but it came up straight away and told me exactly how many weeks".
While it's a fairly simple display, it indicates how many weeks pregnant you may be, with different lines showing how far along the pregnancy is. Reviews were mixed on the displays, with some finding them a little complicated and unclear, while some preferred them to the digital displays of other tests, so it depends on your preference.
Pros
- Offers the option of using it as an inflow test or dipping it in a cup
- Results come through in 3-5 minutes
- Different lines show how far along the pregnancy is
Cons
- Some reviewers found the displays a little complicated and preferred digital options
| Number of Tests: | 1 |
| Display Method: | Line |
| Results Time: | 3-5 minutes |
| Sensitivity: | 25mIU/ml |
How do pregnancy tests work?
It's actually pretty simple!
Pregnancy tests essentially work by checking your urine for a hormone called human chorionic gonadotropin (hCG), which is a hormone that your body only makes if you're pregnant. This hormone is released when a fertilised egg attaches to the lining of your uterus and when pregnancy begins.
Home pregnancy tests look for how much hCG is present in your urine. At-home pregnancy tests usually involve placing drops of urine onto a chemical strip, placing this strip into your urine or holding the test in the flow when you go to the toilet. The strip then detects hCG, and you will need to wait a certain amount of time before the results show in the test window.
How soon can you do a pregnancy test?
If you're dreaming of being pregnant, it's understandable that you might be keen to take a test as soon as possible, but it is worth waiting a little while. Even if you've experienced pregnancy symptoms such as an increase in wet, watery discharge, pregnancy fatigue, or period pain but no period, it's important to be patient. Experts suggest waiting to take a pregnancy test until the week after your missed period for an accurate result, as this is when the test will be most reliable. If you are pregnant, your body needs time to develop the HCG hormone so that it can be detected.
Dr. Irina Ilyich, Medical Advisor at Flo Health notes that "with clinically sensitive urinary pregnancy tests, it is possible to detect pregnancy up to 4 days before the expected period. However, not all commonly sold home pregnancy tests offer the promised clinical sensitivity. Most urine tests are not sensitive enough to detect hCG until about 15 days after fertilisation. Usually, these are the first days of menstrual delay."
If you do not want to wait until your period, then you should wait at least 21 days after you’ve had sex. Some pregnancy tests can be used from as early as 8 days after conception. However, for accurate results, it’s best to take a test when your period is due and, of course, if your period hasn’t arrived. If you take a test early and get a negative result, you may still be pregnant but not producing enough hCG for it to be picked up yet, so if you are testing early, it's worth having more than one test so you can do reruns.
How accurate are home pregnancy tests?
Generally, pregnancy tests are pretty much on the mark. Pregnancy tests are usually 99% effective, which is the same accuracy rate as most urine pregnancy tests performed in a doctor's office.
According to the NHS, a positive pregnancy test is "almost certainly correct. However, a negative test result is less reliable." Dr. Irina Ilyich notes that this could be an error in following the instructions or taking the test too early. For example, testing just days after ovulation could result in a false negative, which means you will need to test again later.
Should you retest?
As above, pregnancy tests are very accurate, and it is highly likely that the test is correct the first time around, provided you follow the instructions correctly. Understandably, you might want the reassurance that the result is definitely correct and choose to do it another time (or several times!). Several positive or negative pregnancy tests may well help the news sink in. We would also recommend checking the instructions of your test again to ensure you are doing everything right.
The number of tests you take is a personal preference, and some women like to take a few to be sure. If you have taken multiple tests and they all give positive results, then it is highly unlikely that something is wrong. We suggest going to your GP for a further test if you are worried, as this will put your mind at ease.
Can I get a pregnancy test on the NHS?
It is possible to get a pregnancy test on the NHS, but normally not at your GPs - you could make an appointment at your local Sexual Health Clinic. It's probably a lot quicker and easier to buy a pregnancy test!
What to do next?
If you have a positive pregnancy test result
Arrange an appointment with your doctor telling them that you took a test and it came back positive. From there, your doctor can guide and advise you on your next steps. You'll be advised to make an appointment with the midwife, where your pregnancy will be confirmed.
If you have a negative pregnancy test result
If you were trying for a baby but had a negative pregnancy test result, try not to get too disheartened. It often takes several months or more to get there finally. If you are concerned about your fertility, please see your doctor.
If you're not trying for a baby, but are worried that your birth control is failing you, see your doctor so that you can find the best options available for you.
