It could be that you’ve waited too long to check the result. We get distracted as the kettle starts whistling or when the phone chimes, it happens! That is why you may experience evaporated lines. Urine samples that have been kept for too long are also unsuitable for the test.
We encourage you to read the instructions before self-administering the test. Also, check that you are not using the twoplus Fertility Pregnancy Test Kit (by Point of Care) beyond its expiry date.
