I used AccuCheck Day One Pregnancy Test and I got a light purple-pinkish line in the test section.?

Could this be...am I pregnant, my husband and I have been trying naturally for 3 months!! And I really hope that this is not a mistake. I plan on retesting on Sunday morning. My period is 2 days late now! I just wonder if any of you have had this as a result and it was indeed possible!!
