HPT BFP!! ?? I am freaking out...?

I got up early this morning and took a first response HPT. One line was very dark and then there was a second line that was extremely faint. I atually only saw the dark like and thought I got my BFN again...but then looked closer and saw the very faint second line. Am I pregnant and there's not a lot of pregnancy hormone yet? Or have I overlooked previous tests and the 2nd line is faint on all of them? What do you think!?
