Help! Multiple positives and then 1 negative?

Ashley

Two days ago I had multiple positive pregnancy tests - including two digital ones! This morning, I took another digital one, a FRER pink line, and an internet cheapie. The FRER and cheapie both had two pink lines, but the digital said negative. Am I actually pregnant?! Am I having a chemical?

The test lines from today are also darker than they were two days ago. Really hoping that digital is a fluke!
