Can I be pregnant ?

Maria
So I am 6 days late and I have taken 2 tests both say negative 1 I took before my period was predicted to come and one 2 days after my missed period I did think I saw a faint line but I thought I was seeing things ... I don't know if I should take other one or wait I feel like I don't want to be discouraged  if I am not what should I do ?
