Can anything cause a pregnancy test to show a false negative?

Question

Okay, so we all know you can't get false positives, unless you're having a chemical pregnancy or if you're taking certain fertility drugs.

But is there anything that can cause the test to show a false negative - apart from low HCG counts? Let's say a kidney infection, or a bladder infection... can those cause false negatives?

Answer 1

unless u are doing the test to early

Answer 2

no it will only be negative if your hcg levels are not high enough or your not pregnant
