You may think that you know all there is to know about at-home pregnancy tests, but may find out that you are unfamiliar with a faint line on pregnancy test.
Before further discussing what causes a faint line on a pregnancy test, it's important that you understand precisely how these tests work for an idea of how you can avoid seeing a faint line on a pregnancy test and wondering if you are or are not actually expecting a baby you so desperately hope to have.
Home pregnancy tests are fairly simple. You take them and they tell you whether or not you are expecting a baby.
However, they're really not that simple. What goes into the makeup of an at-home pregnancy test can be quite complicated.
For example, tests often show false negative pregnancy results.
False positive results are very rare but do occur.
Tests can expire, they can work incorrectly and if you don't take the time to read the specific instructions for that particular test you are more likely to misuse the test and experience incorrect results.
If you take a test immediately after you think you conceive, the test will not work.
It takes as much as a full week before your fertilized egg makes its way into your uterus and implants itself on your uterine wall.
Your body does not begin to produce hCG until that egg is fertilized and implanted on the wall.
At that point, it still might not be possible to get a positive pregnancy test result.
Because every test is different and each one is created to read different levels of hCG.
You are considered pregnant if your hCG levels exceed 5 mIU.
However, it takes anywhere from 48 to 72 hours for hCG levels to double and most at-home pregnancy tests are not sensitive enough to detect pregnancy until your levels are around 25 mIU.
This means it could take a week or two after your egg implants to tell that you are pregnant because hCG levels rise at different rates.
The first step is to carefully read the instructions. Each test works the same way, but requires a few different considerations.
For example, some tests allow you to hold the test in your urine and others allow you to use a cup.
Some require you hold the test for this many seconds and some require you do so for less time.
Other tests ask that you hold a test a certain way and lay a test on the counter in a certain direction.
Every test tells you how many minutes you have to wait before you can read the results and exactly how long those results are accurate before chemicals and time change the results of the test.
Not following the instructions to a tee could mean that your test is invalid.
Here's what you need to know about faint lines...
Faint lines are lines that appear in a test after the test has been used and sitting for a while. This is why manufacturers insist that you only look at the results during a very specific time frame.
When your urine begins to evaporate from the test strip with time, it leaves a faint line in the same location a line would appear if you are pregnant.
This line is called an evaporation line. Many women look at their tests and see a negative result, save it and look again hours later.
If there is a second line on the test hours later, it's an evaporation line. It's not a pregnancy indicator.
If you do not see a positive result inside the allotted time frame discussed in the instructions of your at-home pregnancy test, throw it away immediately.
Keeping it and looking at it later might give you false hope. False hope will cause you to think you might be pregnant because a second line appeared, but this line does not mean you are pregnant.
Pregnancy tests are very accurate when used correctly. But, remember, they must be used at the right time of the month.
Too early, and a false negative result will occur, due to the need for the pregnancy hormone to be present in a high enough quantity for the stick to measure.
If your menstrual period is two weeks late, and the pregnancy test is still negative, an appointment with your doctor might be necessary.
