Tested again

Hannah
So with all that has been doing in with having the spotting and having them tell me that I am a week later than I thought and both being blue to see a fetal pole or heartbeat at 5 weeks 2 days (I know they said that pretty normal but I am still worried) so I took another pregnancy test today this afternoon reLly I am not sure if that matters but it was positive but the line was not as dark as the first one I took about a week ago! Is this bad or am I just worring over nothing? I get my levels tested again tomorrow they where at 6566 yesterday so hopefully they have doubled and I am just over worried?!
