There are a few reasons for faint lines on an at-home pregnancy test. You could have taken the test too soon, your urine was diluted, you were using a sensitive test, or you experienced a chemical pregnancy. To ensure better clarity my suggestion is to buy a more expensive test that clearly reads "pregnant" or "not pregnant" or you could buy some other form of a digital test. That will help with any confusion that might occur with pregnancy tests that require you to read lines or dots that may appear faint.
There are several things that can contribute to a negative pregnancy test even if you are pregnant. Some medications can give you a false negative, the timing of the test can affect the results. If you did not follow directions properly; if you let the test sit for too long the results may read negative after a while. It is important to read the results within the amount of time given on the instructions of that particular pregnancy test you bought. If you did not perform the test properly (example: you drank a lot of fluids before taking the test, which can dilute your urine). Etc To ensure the best results: * Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest * Don't drink a bunch of fluids before taking the test because it will dilute your urine and can affect the results * Take the test no more than 1 day before expected period. Although some test say that you can see results up to 5 days before your missed period, the percentage of accuracy is very low. * urinate for as long as possible on the foam-like strip * Check the results in the window frame of time suggested by the instructions of the pregnancy test. . On rare occasions you can encounter a false positive due to improper testing, expired pregnancy tests, rare medical conditions such as certain types of cancer, evaporation lines, a recent pregnancy or a chemical pregnancy.

The residual for a particular point in a regression is negative if the estimated or fitted value at that point is greater than the observed value.
In order for that to happen, one object must be positive mass and the other one must be negative mass. Negative mass has never been observed yet, so gravity has never been observed to push objects apart.
currently, it raises "noise" in a photo. In a few years, there's a good chance there will be no negative effect.
The Negative Effect of Crystallization is laser damage in high resistance mirrors. A grain boundary of HfO2 microcrystal was observed in the damaged area.
A negative z-score indicates that the observed value (or statistic) was below the mean. In non-directional tests, a negative z-score is just as likely as a positive one.
The enthalpy of mixing for this mixture is negative: and the mixing is an exothermic process in this case.
Positive cardiac activity means the doctor observed the baby's heart beating.
He hypothesized that cathode rays are streams of electrons or negative charges
A negative control is a control group in an experiment where the variables are not expected to have an effect. It helps researchers to determine if any observed effects are due to the treatment being tested or other factors.
9f you are using the equation %error =[(oberved value - true value)/true value]x100 a negative percent indicates the observed value is less than the true value by the calculated percent.
An analogue meter will deflect the needle the wrong way. A digital meter will show a negative value.
