what does this mean?

yesterday i used a cvs pregnancy test and i accidentally peed on the result window and the part you’re supposed to pee on, it immediately started to turn the pregnant circle light blue (not a line just the entire circle) it then disappeared and said not pregnant. when i checked back later there’s a line but i can’t tell if it is blue or gray... it is just as thick as the non pregnant line and i’m very confused. i’m supposed to get my period tomorrow but it is sometimes late. i’m very stressed out about this, what do you guys think?
