Can anything cause a false positive pregnancy test?

What happens if you pee too much on a pregnancy test?
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.

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.
