Freak out! Faint lines??

Okay so I went to the doctor almost 2 weeks ago and was confirmed that everything was progressing fine. They didn’t wanna see me back, but needless to say I’m paranoid due to my past 2 miscarriages. I read into everything and I know stress isn’t good, but it can’t be helped. I’m almost 5 weeks and today my boobs just weren’t as sore. I’ve been having very light cramping/twinges but no spotting. So I took a pregnancy test when I got home from work. The line looks more faint than it did when I took one on Saturday! Then I read that sometimes the lines can get lighter when too much hcg so diluting it and retaking it might make it darker. I tried that and the test looked slightly darker than the one before but I’m just so worried now.

First one is Saturday, second is today before dilution, third is diluted today.
