Help! I'm so confused!

Jennifer
I took 1 pregnancy test yesterday morning with a faint positive and 3 last night that you could see clear positives on. This morning I took a digital and it says not pregnant. I'm so confused. I took 3 test that look to be positive after the digital. Is it too early to take digitally? Could I have done it wrong? I have light brown spotting. I want this so bad. If anyone has any advice or knows why this happened please let me know. I'm driving myself crazy. Top picture is from this morning. Bottom is from last night.
