I have had 2 readings with yona, and usually the things she brings up in the very beginning of the readings and things she sees for “the immediate future” happen quite quickly. Within weeks of the reading. Anything after that seems to take a bit longer...
My first reading with her (Oct 2017), the things she mentioned in the beginning happened right away. Within 4 weeks but all the stuff after that just started happening I believe about a month ago -ish
Second reading, same thing happened. She did pick up on something that had recently happened in the past but her “immediate future” predictions happened around the 4 week mark again.
