It might be an INVALID test!
Let’s find out why.
What Does an Invalid Pregnancy Test Mean?
An invalid pregnancy test means the result is unreliable.
No control line = Test is not working!
Blurry or missing lines = Possible error!
How a Pregnancy Test Works
Pregnancy tests detect hCG (pregnancy hormone) in urine.
Two lines = Positive
One line in control window = Negative
No lines or only test line = INVALID!

Not enough urine on the strip
