Faint line on pregnancy test 5.5 weeks

So I am trying to stay positive and calm. I am pregnant with my second, and just don't feel pregnant like I did the first time around. I decided to take a test after not taking one in well over a week and the line was very faint. The test I used today was First Response Rapid Detection and very faint pink. I took a Clear Blue last time and had a very strong blue line.  Today I tested in the afternoon, the others have been first morning.  Is this a bad sign? I'm hoping no and strong healthy pregnancy....
