You’re pregnant Some women see a clearly distinguishable positive line after taking a home test. But in other cases, the positive line appears faded. In these instances, a faint positive can be caused by low levels of the pregnancy hormone human chorionic gonadotropin (hCG). There are several reasons that a pregnancy test might fade, including: Time. Depending on the test brand and type, the chemicals in the test strip that caused a reaction with your urine may evaporate. That doesn’t mean you’re not still pregnant. Ectopic pregnancy is uncertain. It can give a positive pregnancy test and then negative because the hCG hormone is not doubling constantly and thus can be erratic. Molar pregnancy also has a similar case when the developing egg doesn’t form the embryo. You may get a positive pregnancy test and then negative.In general, conditions, when a home pregnancy test shows one line, it means that the test is negative and you’re not pregnant, whereas, two lines mean positive, you are a to-be parent. The faint positive, however, is a result window that can leave you scratching your head.Pregnancy tests show evaporation lines due to evaporating urine in the pregnancy test window. There will be a very faint line on a home pregnancy test when the urine on it begins to dry up and vanish. This faint, colorless line can appear on any at-home pregnancy test.
Can a positive pregnancy test line go away?
An evaporation line does not indicate that a woman is pregnant. These lines often occur when a person has checked the result too late or taken the test incorrectly. When an evaporation line appears, it is best to take another test for an accurate result.
Why is my positive pregnancy test fading?
What causes faint positive lines on a pregnancy test? The strength of the positive test line depends on how much hCG is in your urine. If the line is faint, it usually means that the hCG level is low. One reason why hCG levels may be low could be because you’re still very early into your pregnancy.
Why did my pregnancy test change from positive to negative?
The hook effect happens when you have too much hCG in your blood or urine. How is this possible? Well, the high levels of hCG overwhelm the pregnancy test and it doesn’t bond with them correctly or at all. Rather than two lines saying positive, you get one line that incorrectly says negative.
Why do pregnancy lines disappear on a pregnancy test?
A pregnancy test can detect the hCG hormone — and if two lines appear, voila, you’re preggo. Reason #1 For Vanishing Lines: You’re Testing Too Early At least, that’s how it’s supposed to happen. But sometimes, a pregnancy line disappears, and it could happen for a variety of reasons, Dr. Kameelah Phillips, MD, an ob/gyn tells Romper.
Why is my a positive pregnancy test coming back negative?
A positive then the negative test can also be because you repeated the test immediately and your urine sample (the second time around) had had a low concentration of hCG. As you know with not enough hCG to detect, the test will be negative.
What does a faint positive then a negative pregnancy test mean?
Faint positive then a negative pregnancy test is also a sign that you made a mistake while taking the earlier pregnancy test. You might have read an evaporation line as positive during the first test.
Can you get evaporation lines after a pregnancy test?
You may get evaporation lines after a test. If you consider them as positive, then you will get negative pregnancy test later. Similarly, if you get a positive pregnancy test after result reading time, then it is invalid.
