Am I pregnant or was it an evaporation lines?

Try a pink dye test. Blue tests are commonly known for evaporation lines, but with my pink test the second really faint line was definitely a positive. Try again tomorrow with your first morning urine, and then go from there. If it's negative go with that, and if it's positive go get a blood test done with your doctor. First Response tests can be taken up for five days before your expected period btw. If your period comes and you still experience those symptoms go to the doctor maybe, it could be an STD or some other illness.
