Please!

I've taken multiple test's and gotten faint line's on all of them but the blood test at the doctor came back negative even though i had a faint positive that morning? I've had chemical pregnancy's in the past and im so scared of it happening again.. I just want a healthy baby!

The test i took the morning of getting the blood test done

Update: i took another test and the line's have gotten lighter so im starting to think it's another chemical pregnancy.. Thank you ladies for your help!
