My digital was positive a few days ago and now I can barely see a line.. or is it just me

Is it possible to have a late ovulation so I won’t be able to know if I am or not for a couple weeks?

It’s so weird to get a positive digital and a line and now all of a sudden it’s not.

Has this happened to anyone else?

Is there still a chance I could be pregnant

I read a lot about this clear blue pink die test and most the time it don’t show color? Please help me try to understand I’ll appreciate all the comments of peoples stories

and what you have to say about my situation
