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.

A false-positive result indicates a pregnancy even though there isn't one. Rarely, the test may detect abnormal, non-pregnancy tissue, which requires follow-up by a doctor. These results are rare because usually only pregnant women produce the hCG hormone.

False positive pregnancy tests are possible but rare. There are some medications and medical conditions that can cause a false positive. For example, if your fertility treatment included a "trigger shot" of hCG, you could get a positive pregnancy test result that doesn't actually indicate pregnancy.

Serious urinary tract infections (with high levels of WBC, RBC and nitrite) can occasionally cause a false positive pregnancy test result. Ectopic pregnancies typically produce lower levels of hCG than normal preganancies. This will be accentuated by the dilution effect in urine.

A positive pregnancy test result will mean you are almost certainly pregnant. Getting a true false positive – when you were never pregnant in the first place – is incredibly rare. ... If you are testing before the date of your expected period, you may be pregnant but your hCG levels are too low for the test to detect.

False negative tests are common. In fact, many women get false negative tests before they get a positive. This is because the body's HCG levels have not yet risen sufficiently high to indicate that a woman is pregnant. In many cases, a woman will later get a positive test if she just waits a few days.

False negative pregnancy tests are much more common than false positives. While a urinary tract infection (UTI) is unlikely to cause a false negative it could do so, at least in theory. If you have a UTI, see a doctor and then retake the test a few days later.

Urine HCG tests often return false-negative results, particularly very early in pregnancy. This can be stressful and demoralizing to people struggling to become pregnant. Blood tests are typically more accurate, though even these may fail to pick up low levels of HCG in early pregnancy.

This scenario is pretty rare, but it can definitely happen. So why were the pregnancy tests negative? One explanation for a false negative pregnancy test is what's called the hook effect. It's not common but sometimes this effect leads to urine and blood tests giving the wrong result.

It is possible to get a false negative on a pregnancy test (where the test says you're not pregnant, even though you are), particularly if you've tested before your period is due. If you've just had one negative result, you could try waiting for a few days and testing again, just to be sure.

Not Believing Positive Test Results If you are not pregnant, a false positive pregnancy test result is unlikely. The more likely explanation is that you had a chemical pregnancy (which produces enough hCG to turn a pregnancy test positive but miscarries shortly after) or a very early miscarriage.
