can you be pregnant and get negative urine test?

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.

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.

There are many reasons you might ovulate later than you typically do. Another common reason for getting a false negative is not having enough hCG in the urine you test. Early on in pregnancy, you can dilute the hormone concentration in your urine if you drink a lot of water before testing.

While urine pregnancy tests can accurately detect the presence of hCG, they are qualitative - merely giving a negative or positive result. Most urine tests need a higher level of hCG than a blood test to show a positive result and so may be slower to show a positive result.

hCG levels can usually be detected in the urine about 10 days after conception. If you take a urine pregnancy test fewer than 10 days after conception, the at-home tests might give a “false negative” response. This means it will show that you are not pregnant when you actually are.

However, negative results are less reliable. For example, if you do a pregnancy test too early, you could be pregnant, but there may not be enough HCG in your body to give a positive test result. Pregnancy tests vary in their sensitivity (how soon they can detect HCG and what level of HCG needs to be present).

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.

If you take a test too early, you may get a false negative (when the test says you are not pregnant but you are). Your body needs time for the hormone to rise to a high enough level to be detected in a test. If the test comes back negative but you still think you could be pregnant, wait a few days and test again.

It's possible to get a negative result from a home pregnancy test when you're actually pregnant. This is known as a false-negative.

Even if you did miss your period but it hasn't been at least a couple of weeks since you conceived, you could still get a “false negative.” That's because you need a certain level of a hormone called HCG (human chorionic gonadotropin) in your urine for the test to work.

A repeated negative pregnancy test even with a missed period typically means that you are not pregnant. A negative pregnancy test a week or more after your missed period indicates that your chance of being pregnant is less than 1-2%.

Factors that could affect results In addition to testing too early, the following factors can cause a false negative with a urine HCG test: drinking lots of water so that the urine is very diluted. getting too much or too little urine on the test strip. testing with urine late in the day when it may be weaker.

A chemical pregnancy wouldn't result in HCG dropping that quickly. A false negative due to dilated pee is much more likely. Early in the pregnancy, you almost have to use the first pee of the morning to get a positive test.

If you take a pregnancy test at night and get a positive result, then you are most likely pregnant. However, if the result is negative, it's possible you might not be pregnant. But you may have also just not had high enough levels of hCG in your urine to be detectable.

Why did I get a negative test result? 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.

If you take a pregnancy test after your period is late and get a negative result, you're unlikely to be pregnant. Home pregnancy tests are very accurate — about 99 percent — but a false negative is still possible. Try taking another pregnancy test in a day or two to double check.

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.
