I wouldn't have any just incase you are pregnant. I had a false positive / evap line with blue colour using a crystal clear. If it is very very faint, I would wait two days and test again. I hope it is though!

For what it is worth, I found a crystal clear test in my bathroom when I was 8 weeks pregnant and thought, what the heck, ill do it to see how bright the line is. And the line was still feint. I know I had at least 75000 hcg in my blood.

I just don't like crystal clear!
