I took a cvs pharmacy one step pregnancy test and in the control windo I noticed a faint blue line, so I put the pregnancy test unde a ultra violet light and the blue line in the control window changed colors from blue to red, but the result window line stayed blue. So, is that positive pregnancy test?

Don't know whether that test was positive or negative since you manipulated it with an ultra violet light.

Next time, take the test using first morning urine. Follow the directions on the box exactly and throw it away after reading it at the time frame required on the directions.
