Pregnancy test false negative is it possible with a clearblue test?

I took a early pregnancy test , I missed two days of my period & still a negative pregnancy test ?

Ladies I have a serious question is it possible to have a Lh test interfere with a hcg test

So I took a pregnancy test yesterday and it looked like a faint positive (took clear blue) then I took two other test today (one $1 and the other generic Walmart brand) and they both came back negative. So do I go off the first one and think it's a possible positive or since there was two negative test and take it as I'm not pregnant? Confused!!

Took 1st response test yesterday had a faint line took Clearblue test this morning text came back negative

Ignore my dirty sink but I just took this Clearblue test and the digital part says negative but I think I see a faint line on the strip that was inside it? Am I crazy?

I took a first responds 6 days sooner test and it was negative 2 days later I took clearblue it was positive

all my pregnancy test is still negative and I don't know how that's possible, I'm very upset rn

I need help please before I determine anything is this a false pregnancy test line are am I pregnant #

i am so confused.. i had 3 very faint positive test but when i got my blood test done it was negative 😞 is it possible the test were defective?
