Positive pregnancy test? False positive?

Katelyn
Well I got my first at home ovulation kit today because my hubs and I are obviously trying for our first baby and my
cycles are pretty irregular. I took two of the ovulation tests and they were very positive! yippee! it is day 15 of my cycle, which is about right for the LH surge. just for kicks and giggles I used one of the pregnancy tests that came with the kit.. this is a negative test right? my eyes are playing tricks on me and there aren't two lines? but every time I look at this picture I took at the 4 minute mark all I see are two lines. I suppose it could be a false positive. I'm just curious to see what all you ladies think. 
** UPDATE **
of course I had to run to the store and buy a pregnancy test to confirm.. so bought a digital and a first response. digital said "not pregnant" and here's the picture of the first response, which looks positive to me. could the digital take longer to pick up huh? I did test in the late afternoon. maybe I should try early morning with the digital? slightly stressing out at the moment.
