Is this positive??

I took a clear blue digital and got a smiley! I got so excited I wanted to check with another clear blue and a wondflo just to confirm...I'm taking clomid so I was so happy I finally got a positive! Any ways the second clear blue was just a circle...a negative. Seriously 10 minutes later is was negative! This is what my wondflo looked like. Granted it was a different urine sample. What do you think?! I'm cycle day 17 and this is the darkest I have seen a wondflo.
