It may be an evaporation line. Read the directions of the test. You should not believe results after a certain amount of time. If in doubt, take the test a week later.

You took a home pregnancy test it came out negative however the negative line is still there and you took it 2 hours ago The directions said that If negative it shouldnt be able to be read after 10 mi?
On a test, there are usually two lines. The one line is what you call the negative line and shows up if you have a negative or a positive result. A test is positive only if two lines show up. The negative line usually stays. The ten minute reference means that the test results after ten minutes will not be reliable. If the result is negative in the first minutes, then that is your proper result.

Why is it that my urine test is coming back positive and negative for pregnancy?
The hCG level is going to be highest first thing in the morning due to urine being more concentrated after not drinking or voiding (peeing) for several hours over night.Throughout the day, depending on how much liquid you consume, urine becomes too diluted (early in pregnancy) to show positive.There is no need to keep repeating urine tests for pregnancy - it is looking for one hormone - hCG - this is only found to be elevated during pregnancy (or with a very rare type of cancer).Once you get a positive test (about 1 week after missing a period) you can rest assured that you are pregnant - repeated tests will not change this, no matter if the tests are positive or not.
