Positive Line on a Pregnancy Test
Most guidelines on the pregnancy tests you buy from pharmacies will instruct you to read their results in a specific time amount, generally after a few minutes.
So, you might take a test and read it within that certain amount of time as positive, then turn negative.
Regardless whether the positive line is clear enough or more fainted, you should always take a second pregnancy test to be sure. Additionally, you should visit your gynecologist for a blood test as well.
Positive Pregnancy Test, Then Negative: No Bleeding
The good news is that whether your pregnancy result was positive, then negative and you aren`t bleeding, you can still be pregnant. Taking into account that a positive test wasn`t the result of a pregnancy test taken after a miscarriage or while on fertility drugs, there are little chances for you to get a false negative.
If you received a positive result and a negative one right after, you might have just made a mistake while you took one of the tests. Your pregnancy test may be expired or just broken. The urine sample may have just been diluted for your pregnancy test to be able to detect the hCG hormone.
In addition, there`s a chance for you to be too early in pregnancy for the test to detect it. Your first test taken when obtained a positive result may have just been more sensitive than the second one. This might mean the first one was able to detect your early pregnancy, while the second one couldn`t.
Moreover, you may have got a negative result with your 2nd test due to the type of pregnancy test you have used. Digital pregnancy tests are most of the time foolproof. This type of pregnancy tests which features lines is harder to read by women. Sometimes the line is so faint that might cause confusion regarding the result of the test.
Can a Positive Pregnancy Test Turn Negative? Why?
Not Take the Pregnancy Test Correctly
If you are doing something wrong while taking a pregnancy test, you might just get a negative result. Positive pregnancy results followed by negative ones don`t really mean that you aren`t in fact pregnant. Actually, in most situations you`ll be expecting a child. A negative result when you are in fact expecting is known as a false negative pregnancy result.
Chemical Pregnancies & Early Miscarriages
Among the most frequent reasons to get a positive pregnancy result the first time and then get a negative one is because of chemical pregnancy, also known as early miscarriage. These are miscarriages which happen within the first 3 months of pregnancy and are experienced by up to 25% of pregnant women, according to BabyCentre.com.co.uk.
Chemical pregnancies are quite common and might offer an answer why during history there was some sort of a tradition not announcing a pregnancy until the second trimester. Symptoms of early miscarriage involve heavier periods, while certain women go through their monthly menstrual cycle without even knowing they experienced a miscarriage.
Different Pregnancy Test Brands
Using distinct types of tests sometimes require going through different guidelines as well. Most of the times, these instructions are rather the same, but exceptions are possible. So, you have to read them carefully in order to avoid misinterpretations in the end.
Obtaining positive pregnancy results, then negative ones isn`t really uncommon when using 2 different pregnancy test brands.
Pregnancy Tests that Are Too Sensitive
As you may already know, regular pregnancy tests bought from pharmacies test a woman`s levels of the hCG hormone. This particular hormone is among the first one that increases while expecting. Lots of women who`ve been attempting to become pregnant for long periods of time tend to use high end testing methods that can pick even the smallest amount of hCG hormone.
If you take a pregnancy test right after conception, the hCG level from the body might be too low, and therefore cannot be detected. Testing at distinct times during a day or consuming large amounts of liquids may also affect a pregnancy test`s result.
Broken or Expired Pregnancy Test
If you take a 2nd test with a different kit, be certain it isn`t broken. A broken test won`t detect the hCG hormone properly. If the control line can be seen, then you can be sure the pregnancy test works.
A pregnancy test that is expired has lost its ability to detect the levels of hCG. These tests have a maximum allowed life, which is about 2 years until they expire.
False Negative Pregnancy Test
Another reason why the 2nd pregnancy test might have obtained a negative result might be because it was broken or not functioned correctly for whatever reason. While this normally isn`t really the case, it could happen in very rare situations.
Instead of taking a test really soon, it`s perhaps better until your menstrual cycle has run its normal course. Waiting until a missed period to take a pregnancy test offers the possibility of more accuracy when reading its result.
Diluted Urine Sample
If you take the 2nd pregnancy test immediately after the 1st test, you may not have enough hCG hormone. This is also due to the fact that only early in the morning urine has maximum concentration of hCG.
A diluted urine sample cannot really offer a positive result during early stages of pregnancy. You may increase your accuracy by using a more sensitive pregnancy test; still, you won`t be 100% sure of its accuracy.
If you have followed an IVF treatment and then took a pregnancy test, you`ve most likely received a false positive result. This is also due to the fact that fertility therapies work based on ovulation medications. These increase the levels of hCG in the blood.
This may offer a positive pregnancy result, then a negative one. The second result is negative generally because the levels of hCG tend to drop after a while.
