Should I Trust It

Ok so i will test again if i don't get my period by next week but i wanted another set of eyes and also your opinion. So i took a pregnancy test yesterday since i was 21DPO today should be 22 DPO. I took the digital test and it said not pregnant so i remembered i had seen a video in tiktok were a girl had taken a digital and had same answer not pregnant. Then what she did she opened the test and took out the strip that shows the lines and she saw a faint line beside the dark one. So i decided to do the same and i can see a faint line, in the picture its a little hard to see. What do you girls think should i trust it or have you girls heard from someone else that had happened to them the same. So first picture it shows not pregnant but second pictures is the strip that was inside the digital test.
