It started off as negative immediately after I peed on it, then gradually picked up a blue hue on the positive line. Verrrrry faint.. then when I left my house and came back several hours later, the blue hue formed into a hard line on the left side (when I took this photo.)

Otherwise it remained a very very light blue and hard to see.

Should this be considered positive? I took a first response and thought I saw something faint but I felt like my eyes were deceiving me.

Advice anyone?
