??Did i pass Stones??

.Yes i did my first flush 7-26-02,and the only thing i saw could have been stones were,very dark green or black mostly round,one of the was a bit large,rest were pea size,they were not real hard but floated for a while then sank,forgive me im new to the board but i know one thing i was in some pain not to bad,but all the pain was gone when i did the flush,no pain at all for three days now.Question?how long should i wait until next flush,i did the epson salt,lemon and olive oil,(90 ounce liquid)they were also lots of other unknown objects the flush would have to be good for you,after the next flush i will have another ultra sound and post results,any info will help..thanks..
