10dpo test. Let me explain

So I took a test today and in the time frame, I saw like a faint color line on the the test, but it wasn’t like a whole straight line. About 2-3 later this is what it looks like... could it possibly be the start of something?? My af is 4 days away and having been feeling like af is coming, so I’m a little worried:( btw I had to take the test out of the frame to get a better picture bc I have a bad camera, but you could see it with it on lol. Last one is what it looks like now.
