Various reasons, from testing too early to experiencing extreme stress, can lead to a negative test result.u0026nbsp; Pregnancy tests have come a long way. Historically, people didn’t have a reliable method of knowing if they were pregnant without going to the doctor.
- It wasn’t until the first at-home pregnancy test was invented in 1976 that people could confirm that they were expecting.
- But despite technological advances, there’s still a lot of mystery about the menstrual cycle,
- You may have a delayed or missed period, but still have a negative pregnancy test.
- In those situations, you may wonder what’s going on.
Are you pregnant? Is something wrong? Here are a few reasons your period may be late, even if your pregnancy test is negative. If you’re trying to get pregnant, there’s good news: You may still be pregnant. Sometimes, levels of the pregnancy hormone human chorionic gonadotropin (hCG) early in pregnancy aren’t high enough for a home pregnancy test to detect.
- One study found that home pregnancy tests only have to detect hCG levels above 25 milli-international units per milliliter (mIU/mL) to achieve the commonly advertised 99% accuracy rate.
- The writers of an older 1991 study calculated that to detect 95% of pregnancies, a test would have to detect levels as low as 12.4 mIU/mL.
But not all home pregnancy tests were consistently sensitive enough to do so. Menstrual cycles can vary widely, so if you conceived later in your cycle, your hormone levels may not be high enough at the time of your missed period. There can be as much as a 13-day difference in when ovulation occurs, meaning that you may think you are 4 weeks pregnant when you’re only 2 weeks along.
- Pregnancy bleeding, recent hormonal contraceptive use, or breastfeeding can all interfere with accurately knowing your dates as well.
- If you think you may be pregnant after a missed period but got a negative result on your pregnancy test, wait a few days.
- Then retest.
- If you continue to miss your period, be sure to talk with your doctor to rule out any complications.
Several outside factors can wreak havoc on your menstrual cycle. Stress, for example, can delay your period. Malnutrition can affect it, too. Your cycle can fluctuate if you drink too much caffeine or don’t eat enough food. Sudden lifestyle changes, such as intense exercise or working the overnight shift on your job, can also cause your period to be irregular.
Breastfeeding can cause some irregularities in your cycle. Even after childbirth when your period returns, it may take some time before your cycle returns to usual. Breastfeeding is also unpredictable month to month. As babies grow, their feedings may change. For example, if your baby goes through a growth spurt and suddenly increases the frequency of night feedings, it may interfere with your cycle.

Can a pregnancy test be wrong if taken too early?
Could a negative result be wrong? – It’s possible to get a negative result from a home pregnancy test when you are pregnant. This is known as a false-negative. You might get a false-negative if you:
- Take the test too early. The earlier you take a home pregnancy test, the harder it is for the test to find HCG, For the most accurate results, take a home pregnancy test after the first day of a missed period.
- Check test results too soon. Set a timer to go off at the time the test directions say you should check the result. Don’t check the test until that amount of time has passed.
- Take the test later in the day. For the most accurate results, take the test right after you get up in the morning. That’s when your urine is the most concentrated, making HCG easier to find.
What Colour of urine indicates pregnancy?
Is there any change in urine color during pregnancy? – Normally, the color of urine can be light yellow or yellow to transparent. But for a pregnant woman, this change is more prominent and noticeable. The urine color can change from light yellow to dark yellow.
It can go to an orange-yellow shade too. Urochrome, also called urobilin, is the component that renders urine its color. When the hemoglobin in our body breaks down from dead erythrocytes, urobilin is produced. When our body is hydrated, and the urine is in a dilute form, the concentration of urobilin decreases, and the urine is lighter in shade.
On the contrary, if there is a lack of water in your body and you are dehydrated, the concentration of urobilin increases, and the color of urine becomes dark yellow. There many more reasons for the change in urine color during pregnancy. Pregnancy has a significant effect on the working of kidneys.
Is urine test good for early pregnancy?
What is a pregnancy test? – A pregnancy test can tell whether you’re pregnant by checking a sample of your urine (pee) or blood for a specific hormone, The hormone is called human chorionic gonadotropin (hCG). High levels of hCG are a sign of pregnancy.
HCG increases quickly in the first ten weeks after a fertilized egg attaches to the inside wall of the uterus. Urine tests for pregnancy are most accurate when you do the test a week or two after you’ve missed your menstrual period, If you take a urine test too close to the time you got pregnant, the test could say that you are not pregnant even when you really are.
That’s because your body may not yet have made enough hCG to show up on the test. You can have an hCG urine test at your health care provider’s office or you can do the test yourself with an at-home test kit, These tests are basically the same, so many people use a home pregnancy test before calling their provider.
If you follow the instructions carefully, home pregnancy tests are about 97-99% accurate. They can give you the results in minutes. Blood tests for pregnancy can be done at your provider’s office or a lab. These tests can find very small amounts of hCG, so they can accurately show whether you’re pregnant before you’ve missed your period.
But hCG blood tests aren’t commonly used to check for pregnancy. That’s because urine tests are less expensive, very accurate, and provide quicker results than blood tests. hCG blood test results may take hours to more than a day. Other names: human chorionic gonadotropin test, HCG test, qualitative hCG blood test, quantitative hCG blood test, Beta-hCG urine test, total chorionic gonadotropin, hCG total OB

The tests detect human chorionic gonadotropin, a hormone that a releases when it attaches to the uterus, explains Alexandra Sowa, M.D., an internist and clinical instructor of medicine at Weill-Cornell Medical College.
That’s what can, on those rare occasions, lead to a negative test result even if you are pregnant—it’s too early for the trace levels of the hormone to be picked up by the test. If you get a negative result and want to be extra sure, take a second test. Just be sure to wait a few days—taking a second test in the same sitting won’t give you a different result.
