How long for a kidney stone to p?

I have a suspected stone, though I haven't had any scans this time as I temporarily don't have insurance right now. I did go to my family doctor about 6 weeks ago when the symptoms started and she thought it sounded like a stone, especially given my history of having them. Mild flank pain that radiated down my side into my groin, hip and leg. I've had many stones before, including one a month prior to this one, so I know *that* pain that you typically get with them, but this time, I've only had mild pain that persists rather than that excruciating pain. I feel like someone just kicked me in my side, it's sore and tender with some occional twinges and zaps of pain, and I also continue to feel it down into my groin. I'm straining my urine and no stone yet. No blood either and I'm urinating normally. How long should I let this go on? I just worry that the stone may be stuck and worry about kidney damage for letting it go too long, but I don't know how long that would be. Any insight is appreciated.
