With some home pregnancy tests, one line means the test is negative and you’re not pregnant, and two lines mean the test is positive and you are pregnant. A faint positive line in the results window, on the other hand, can leave you scratching your head.
Does it matter how dark the line is on a pregnancy test?
The darker line is usually the control line. Sometimes this second line is so faint, you can barely see it. If there is a line, not an evaporation line, but a true line, no matter how light, you should read that as a positive pregnancy test.
Can a very faint line be negative?
And, if you wait a day or so (more, if you can bear the tension), your very faint line may well have become a nice, dark one. However, occasionally these follow-up tests may come up negative. If this happens to you, it probably means you’ve had a ‘chemical pregnancy’ – or a very early miscarriage.
Can anything make a pregnancy test positive?
In very rare cases, you can have a false-positive result. This means you’re not pregnant but the test says you are. You could have a false-positive result if you have blood or protein in your pee. Certain drugs, such as tranquilizers, anticonvulsants, hypnotics, and fertility drugs, could cause false-positive results.
How do you tell if it’s an EVAP line or positive?
Positive Result: If positive for pregnancy, there will be one horizontal line intersected with one vertical line, forming a plus sign. The evaporation line typically shows up as a very faint, thin and almost colorless vertical line. If you test early and have low levels of hCG, the vertical line may be faint.
Does a very faint second line mean pregnant?
If you check your results within the recommended time frame and see a faint positive line, you’re most likely pregnant. On the other hand, if you miss the window for checking the results and you don’t check the test until 10 minutes later, a faint line may be an evaporation line, which means you’re not pregnant.
Why did I get a faint positive pregnancy test then a negative?
Sometimes a woman gets a positive test followed by a negative. This sometimes happens when one test is less sensitive than another. But if a positive test is followed by several negative tests, this could mean the woman is having a chemical pregnancy.
How long after a faint positive should I test again?
So, if you do get a faint line, Kirkham recommends waiting two or three days, then testing again. If it’s still faint, she suggests going to your family doctor for a blood test, which can measure the specific amount of beta hCG, to check if the pregnancy is progressing as it should.
What is weak positive pregnancy test?
Test results explained
Occasionally, a laboratory may report a test as ‘weakly positive’ or ‘indeterminate’. This is usually due to a very small amount of the HCG hormone being present in the urine, for example very early in a pregnancy, or when a pregnancy has miscarried.
How many pregnancy tests should I take if positive?
You don’t have to take another test if you get a positive result, but many women choose to repeat the test just to be sure. If you do get a positive result, book an appointment with your doctor or midwife.
How rare is a false positive pregnancy test?
Most home pregnancy tests are reliable, for example Clearblue’s tests have an accuracy of over 99% from the day you expect your period, and while it’s possible a test showing a negative result is wrong, particularly if you’re testing early, getting a false positive is extremely rare.

There is visible dye in the line, even if the color is faint. The line appears within the period specified on the instructions, which is usually 3–5 minutes.
Can a pregnancy test turn positive overnight?
The chemical composition of the urine sample changes due to evaporation. As a result, the test may start to display a positive line. After the allotted time has passed, you should discard the pregnancy test to avoid confusion.
Do you get evaporation lines on every test?
How to identify an evaporation line on a pregnancy test. Evaporation lines are common on pregnancy tests, but they don’t appear every time. It depends on the chemical makeup of each woman’s urine.
