Chemical pregnancy?!

Lauren

Does anyone have experience with chemical pregnancy that could give me some advice, I got a positive pregnancy test 2 days ago (picture below) but my lines never got darker and actually got lighter instead. I started bleeding last night which definitely looks like my period but I’m still getting a faint line. Is that normal? Will it take a while for my levels to go down? Here are my tests.. any advice is appreciated🙏🏼
