Advice on a wonky test please

Kristine
Good morning! I took a pregnancy test bright and early this morning and my partner and I think we got a error test or I messed something up somehow because the control line showed up but in the circle where it shows whether or not your pregnant turned blue. The whole thing. Now I know something went wrong but wouldn't it not turn blue at all if I wasn't pregnant. I know I need to take another test but I can't until Thursday so I was hoping for some advice. Help?
