They are most likely positives. That happened to me before and I thought that it was an evaporation line but since it had color to it, it really was a positive. I did tons of research and that was what I found out. Evaporation lines are colorless and if there is color it will be a whitish or a grayish color. If it is blue or pink (or whatever color that indicated that it is a positive) then it is most likely positive. I took a digital test six days later and that time I got a clear blue line and now I am not 6 weeks and a day pregnant.
Also there is a possibility that you may have gotten a false positive, but those are rare. I would go to a clinic and see a specialist or go to your doctor.
Good Luck!
