Yes or no

Hello ladies. I’ve had a look around and now I have a question too. I did a test and, as expected, only one blue line appeared. Then I left it for my husband to look at, and the second line became very faint light blue. As a first-class nervous wreck, I’m so terribly afraid that it didn’t work out or that something is wrong with me. Could you maybe help me out? Have you had experience with such a result, etc.?
