Faulty test?

Alyson
I took a hpt this morning, I am 8dpo with a short luteal phase. I am pretty sure this is a faulty test and that the line is an indent. Also, the two lines are way far apart! Any thoughts? When I tweak it, there is aline that appears and I have seen posts before that an indent won't do that? Has anyone else has this happen? What was your outcome?? thanks ladies!!
