Digital Pregnancy Tests

So today I decided to take a pregnancy test just for shits and giggles and it came out positive... I took the only 2 other tests that I had that were also digital and they too were both positive... I want to believe that I'm pregnant but something just doesn't seem right... I take 3 digital test out of nowhere because I've been feeling off and they all 3 turn out positive. I am currently 8 DPO. Is it possible for digital tests to be highly sensitive? Should I trust these results? I'm going to test again tomorrow but I just don't know if I should trust the results from the 3 digital tests. Any info you can give is HIGHLY appreciated!
