OPK results meaning- answer please ?!

Lena • Mom of a handsome BOY
I have one quick question. I know when you take an opk if you get a faint line is negative. But I've read from others that have had a faint line and keep hopes that they will ovulate in the following days.
​Based on this, if I get a faint line does it mean that I am close to get a dark line in the next days?  For instance, is there any chance that let's say at the begining of the cycle I'd get only control line, close to O I'd get faint line and finally close to O a dark line ?? Or a faint line is negative and there is nothing more to think about it??
​Please..  
​Thank you ladies!
