EVAP, BFP, LINE EYES? Thoughts please!

Hi ladies!

Yesterday I took a flat First Response thinking I wasn't going to see anything, but I instantly saw a shadow as soon as I tested.. Of course first thing this morning I retested using the second test in the first box and I saw a line instantly, much darker than yesterday! Naturally I went straight to Target after work this evening and bought more! I was so anxious that I couldn't wait until tomorrow morning to test (I'm a POAS addict) and I saw another faint line!

I have no idea when I ovulated this month as I thought we were out due to my boyfriend traveling quite frequently, so I decided to take a cycle off, but AF should be rearing her ugly face within the next couple days! Any thoughts on these tests? The top is from this morning, the bottom is from this evening! I'm driving myself crazy!
