Can First Response show false positive?
There is always a little faint line that shows up so you are tempted to take more and more tests. It’s a rip off and i would never take these early again! It’s one thing to wait until a day before your period but not 6 days sooner because it WILL give you a false positive and you get excited only to be let down then.
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.
Can you oversaturate a pregnancy test?
Although many factors can contribute to a false-negative pregnancy test, the hook effect occurs when the woman has a high concentration of human chorionic gonadotropin (hCG), the pregnancy hormone. The high levels oversaturate the test and result in a false negative.
Why do I feel like I’m pregnant but the test says negative?

Even if you did miss your period but it hasn’t been at least a couple of weeks since you conceived, you could still get a “false negative.” That’s because you need a certain level of a hormone called HCG (human chorionic gonadotropin) in your urine for the test to work.
