I think I smell like poop when I didn't go poop. do I have a problem?

this is going to get detailed. sorry

well yesterday I had to go to bathroom bad. I went and I wiped until there was nothing. then I took a shower. I washed it for like 15 min. then time went by I ate and was sitting here and I got a wiff of poop. I didn't fart or go. I don't know wtf to do. I'm getting devastated by this problem.
