Evap line or a Positive?

Jody

I need opinions I haven't had my period in 2 weeks was supposed to start on the 18th of August been having slight cramping, slight headaches, and my breasts are starting to be a little tender! Last week on Wed and Sun I took a test both were clear as day Neg! This morning I took another test and saw a faint pink line! Anybody have any thoughts? :)
