Is it normal that i think i smell around people?

I actually do have a social anxiety disorder. But besides my disorder I really think every time I'm around people I smell. Because I can tell because it seems like people don't want to be around me and when people walk past me they act akward. People also keep sniffing around me as if I smell bad. I take a shower once every 2-3 days and brush my teeth all the time. I'm sure my breathe dosen't smell. I've smelled my clothes and they don't smell. I don't know what it is I'm thinking it may be bowel movements because of anxiety but I'm not exactly sure.
