If your period doesn't begin, take the test again in a few days or in one week. It's especially important to do this if you took the test before or right after a missed period. You continue to get negative test results, but your period doesn't start. Or you still think you might be pregnant.
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.
Though it is now known clearly some chemical reaction takes place when you pee on the strip which contains hCG antibodies in the strip. Once this chemical reaction has taken place, it cannot occur again. It is best to dip in the urine once and discard it.
Some women think that these kits are often safe to reuse and try to pee on them twice round to verify their results. Unfortunately, this action has no scientific backing and cannot be done. A digital test kit doesn't give lines as indicators of pregnancy but rather, shows a digital sign that you simply need to read.
Can Too Much Pee on a Pregnancy Test Make It Negative? Urinating too much on a urine pregnancy test should not cause a false negative result. But diluted urine, or urine with a higher water content, can impact a pregnancy test by skewing results.
However, you don't need to stress too much about taking a pregnancy test at a specific time of day. Using urine later on when it's less concentrated may only “hypothetically delay a positive result by only 12 to 24 hours,” advises Dr. Flanagan.
Don't Drink A Lot Of Water Before Taking The Test
Diluted urine tends to also have diluted hCG levels which can skew the test results. Take a test when you naturally need to pee. This way, you'll avoid diluting your hCG level and getting a false 'Not Pregnant' result.
While Clearblue does not currently manufacture a reusable pregnancy test, the company spokeswoman said that she would “not rule it out in the future.” Pregnancy tests tend not to be used repeatedly, she added.
The flip side: False negatives
The earlier you test, the higher the chances that this scenario will occur. If you get a false negative but still suspect you're pregnant, repeat the test in a few days. If it's negative again but your period still hasn't arrived, book an appointment with your healthcare provider.
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.
But she cautions that early, constant testing can be misleading—while the tests are more precise than ever, they leave room for false positives immediately after ovulation, when an egg has been fertilized but hasn't yet implanted.
Home pregnancy tests can be up to 99% accurate. However, in some instances, they may produce a false-positive result. Incorrect test usage, previous abortions and miscarriages, and some medications may lead to a false-positive pregnancy test result. People should always see their doctor after a positive pregnancy test.
Test too early and the amount of hCG in your urine isn't detectable. As many as 9 out of 15 women will get a false negative until seven or eight weeks of pregnancy.
Most pregnancy tests include instructions that encourage you to wait at least one week between a negative test and taking another pregnancy test. This is to allow time for your body to build up enough hCG (human chorionic gonadotropin) to be detected in your urine.
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.
If we suspect that a biochemical pregnancy has occurred you may be asked to attend for a repeat hCG blood test or to perform a repeat urine pregnancy test at home. This is usually done 7 days after your initial test but may be repeated sooner or later depending on the clinical scenario.
Any positive line, no matter how faint, means your result is pregnant. Levels of hCG in your body will increase over the course of your pregnancy. If you test early, your hCG levels may be still be low and you'll see a faint positive line.
A doctor will interpret the results as 1-2 meaning you are 3-4 weeks pregnant, 2-3 meaning you are 4-5 weeks pregnant and 3+ meaning you are more than 5 weeks pregnant.
Should I dip my home pregnancy test in urine, or pee on it? Most tests allow you to either place the absorbent tip in your urine stream for (usually) five seconds or dip the tip in a collected urine sample for five to 20 seconds. Accuracy is not dependent on the method as long as you follow the instructions.
Fertility medication or other medicine that contains HCG might affect home pregnancy test results. Most medicines, though, including antibiotics and birth control pills, don't affect the accuracy of home pregnancy tests.
In general, the best time is when you have your first morning pee. However, some pregnancy tests are sensitive enough to detect HCG no matter what time of day you take the test. When possible, try to wait until it's been three hours since your last pee before you take the test.
An evaporation line (or evap line) typically appears like a faded streak, while a faint positive test result looks like a lighter blue or pink line, depending on the test dye color.
The test result should be read as soon as possible after waiting the 2-5 minutes. A positive result will not disappear. A negative result (1 pink line) will last for 10 minutes. After the 10 minute period, disregard any further changes, it is still a negative result.
Menstrual irregularities, such as missed or late periods, occur in 14–25% of women of childbearing age. They can result from a range of conditions besides pregnancy, including hormonal imbalances, hormonal birth control, stress, weight loss, trauma, and certain health conditions.
