HELP!!!! positive or evap line??

Na
On October 1st, i began taking vitex berry herb to aide in my fertility.. 
November 17th, I took a pregnancy test since I began the herb; within 2 minutes I noticed the faint line. (Both pics, one test) 
I broke down crying bc I've been trying to conceive for years! My only child is 9!! 
I sent the pictures to my sisters, one being a surrogate mother and she insists I'm pregnant. I was on the phone with my sisters for about 20 minutes. I returned to the restroom and the line was gone or so I think it was. 
Took a 2nd test the following day, and no line! Haven't taken another for fear of reading negative.
