In brief: Normally 2 days

The time to pass a stone is really the same for men and women.
Most stones pass in the forst 48 hours. The chance of it passing after a week is around 50%.

In brief: Hydration first!

The size of the stone does not correlate well to the intensity of the pain.
The nearly unbearable pain of "ureteral colic" is from spasm of the muscular ureter. Although 50% probability to pass on its own within a few days, a 6mm stone sometimes will get stuck and fail to progress. Usually after 5 days, i recommend having the stone extracted with a ureteroscope as an outpatient.
