Am I pregnant??

I took 2 tests. the first one i took is the bottom one in the photo and i barely peed on it and nothing showed up on it. i checked on it 30 minutes later and it had that one thin line and a faint line next to it. Is that a false read? the second stick is the one on top and i made sure i peed on it a lot. it showed up pretty quickly with just that one thick pink line. is it possible that i am or no because the first one is a false read seeing as it took 30 minutes to show the lines.
