Weird symptoms after 6th flush...

Hey guys! Well I basically feel pretty fine, no big deals or anything. However, have noticed that I have had a LOT more gas this past week than I have had in a long long time. Anyone else experience this after a few flushes? I have done six so far. My last flush was different. More sludge than ever and 4 very large stones came out. All stones were tan this time also, instead of green. Is the gas just a coincidence or maybe I've eaten something that is causing it and I just don't know what. It has a very different smell (not pleasant whatsoever) than my normal gas too. I also have noticed that I haven't been having bowel movements very well and when I push at all or strain, it sort of hurts like it's pulling on something or something is attached, if that makes any sense at all. I don't feel like I have any stuck stones or anything though. Well, just thought I'd ask in case someone else has encountered this. Thanks!
