You can get a negative result on your pregnancy test for two reasons: You are not pregnant or you are pregnant, but you tested too early for the pregnancy test you used to pick up the hCG 'pregnancy' hormone in your body.

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. This error might happen even after you've had one positive pregnancy test and test again a couple days later.

It's possible to have a positive pregnancy test even if you aren't technically pregnant. This is called a false positive. It's sometimes caused by a chemical pregnancy. A chemical pregnancy occurs if a fertilized egg, known as the embryo, is unable to implant, or grow, very early on.

Modern home pregnancy tests (which use a urine sample to detect the presence of human chorionic gonadotropin or hCG, a hormone produced during pregnancy) are fairly reliable. So most of the time, getting a negative result on a pregnancy test means that you are probably not pregnant.

In fact false negatives – where the pregnancy test says you're not pregnant but you actually are – are more common than false positives. However, it's also important to say that this shouldn't give you false hope. A negative pregnancy test is still most likely to mean you're not pregnant.

False negative results (test is negative, but you are actually pregnant) usually occur if the blood pregnancy test was performed too early (a rule of thumb is that it takes at least 7 days after conception for the test to show a positive result).

A negative hCG result means that it is unlikely that a woman is pregnant. However, tests performed too early in a pregnancy, before there is a significant hCG level, may give false-negative results. The test may be repeated in one week if there is a strong possibility of 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.

A negative result can mean that you are not pregnant, you took the test too early, or you took the test wrong. Pregnancy tests vary in their sensitivity (how soon they can detect the hormone hCG), and you may not have given your body enough time to produce enough hCG hormones that will show up on the test.

A pregnancy test works by detecting the hCG hormone, which is usually only present in your body if you're pregnant. Your hCG levels will increase over time if you are pregnant. A negative pregnancy test result means the test hasn't detected hCG in your urine.

If you're testing before the day of your expected period, you may see a negative result – even if you're pregnant – if: Your test wasn't sensitive enough for early testing. You didn't use the first urine of the day, so concentration of hCG in your urine wasn't high enough.

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.

Your hCG levels will increase over time if you are pregnant. A negative pregnancy test result means the test hasn't detected hCG in your urine. If your period is very late, or you've skipped your period, and you get a negative result, you are unlikely to be pregnant.
