Nearly all the stones I flushed out in my first flush were white calcified stones. They were mostly about 1cm in length. I was shocked because I didn't even know I had stones.
I think my flush worked so well because I took Julia's herbs for about 6 weeks prior to the flush. However, She told me to finish the whole bottle of GCG but I couldn't wait so I flushed after I'd taken a third of the bottle. I followed her flush procedures and all her instructions (I talk to her on the phone regularly). I trust her because everything she has told me has happened.
I think you should try the flush.Good Luck.Don't be nervous.It's quite simple really.
