Postive or negative?

I took two pregnancy tests today, I dont think Im pregnant but the paranoia definitely is delaying my period which is annoying. The pregnancy test I took would give a + or -. The first one was a strong -, the second one though has a long horizontal faint line. I didnt notice it until I took a picture of it, tho I took it with flash because my bathroom was too dark, I dont know if its the dye from the test or I really could be pregnant which is freaking me out. The one Im talking about is the one on the left. Its very faint and it drags across the test, I doubt it is a plus. Please give me your opinion to see if I should get a blood test or just let it rest. Thanks for reading.
