What causes the entire circle to be blue?

Okay so I have missed my cycle and had spotting for not even a entire day about 2 weeks ago. I havent been feeling myself at all, I took the blue test first and I seen a line pop up but when the line was all around it was blue. Didnt read past time frame either or before it was finished processing. Took a first response with same urine and I seen the faintest slightest line. Any help ladies also sorry for dirt nails. Havent washed since playing in the sand with my daughter today
