First pregnancy worries

Hannah

I am 5w1d and have been nothing but excited!! For some reason today I decided to take a third test just for fun, and noticed the line is fainter. The top two were taken 5 days ago. Is this anything to worry about? All of my pregnant symptoms have remained the same. I have been trying to think only positive thoughts but this is making me worry? My first appt is 1/12 so I'm hoping for some definite confirmation then!
