Im having bad bowel movements for a few weeks now and bloated feeling and also feeling nauseua ?

Possible infection: I am not sure what you mean by "bad" bm's but it sounds likely that you have some type of infection, possibly any number of bacteria or parasites &/or yeast overgrowth. Stool cultures & parasite tests may show the cause, so it's best to see a doc, but you could try probiotics, broad-spectrum anti-microbial herbs like garlic & ground papaya seeds (2 tbsp once a week x 3 wks), then see doc if needed.
