Okay so yesterday my husband joked that I may be pregnant so u though F it I got a test so I'll make sure I'm not...

It was negative, today I was curious and decided to just look at the test and not sure if my eyes were playing tricks but I think I saw the faintest line and it didn't look grey.

I have 3 beautiful children and do not want another, hubby has said he's going to get a V but with everything going on its not a priority I'm usually soo carefu as to when we have sex but only using the pull out, also for the life of me can't remember when I was on last.

Long story short. Is it possible for a negative test to turn positive?
