Go to the doctor and get a blood test sometimes it doesn't show in an average pregnancy test
What brand have you been using. I am about 2 months late and just been spotting really light pink. I test with first response nothing. So I tested with clear blue and faint line. Some ladies can't get anything on pink. I heard not to use blue tests since they aren't accurate but I also heard some ladies can only get something on blue dye.
I've heard of people showing negative in every pregnancy test that you pee on throughout their whole pregnancy and it only showed up in a blood test !
