2 FRPT showing faint positive results, digital saying "Not Pregnant"; (

I took 2 frst response pregnancy tests, one on 3/14 & the other on 3/15. Both show a very faint positive so I decided to take a clear blue digital test but it came up negative. . I of course started to google and now I'm worried that maybe I'm having a chemical pregnancy or something? Idk! I REALLY want to be pregnant and I got so excited when I saw those 2 faint positives but now I'm wondering if I'm one of those cases of a rare false positive.. :(
