After colonoscopy completed - question about stool

I had a colonoscopy done today.  My prep was movi prep that I followed to a "T".  After the procedure was done, the doc told me that I had 2 polyps that were very small, they were removed and being biopsied.  He was not concerned about them but did have pre-cancerous polyps removed 3 years ago.  He did not say my prep was bad or that he had any problems.  However, this afternoon I was still passing air, fluid and twice had some solid stool come out.  Do you think this is a problem?   I feel fine but worried that since I had some solid stool, although, not a lot, that the doctor couldn't see what was there.  The person next to me was told that her prep wasn't great and she had areas that couldn't be seen
