Trust the digital or not?

I took a cheap dollar tree test last week and saw a vfl. The next day I tested with a digital and it said not pregnant. The following day I retested with a cheapie and again saw a faint line.

I’ve seen YouTube videos of women taking pregnancy tests and opening the digital to look at the strips.

I just took another digital and it says not pregnant. I opened it up and I see the faintest test line on it.

Could I actually eat pregnant????
