Loose stool

This usually only happens when I'm on abx bt im not right now because we are rebuilding my gut 1st. I dont have diarrhea is the odd part it's usually akttle constipation or just not pooping every single day. Well today when I woke up it was like a slime ball or crap that just slipped out like a really loose bowel. I didnt even realize I had to go because I didnt feel I had to go, it kind of was like I wasnt in control of my bowels, like soft mucus just slipped out accidental, sorry to be graphic lol.has anyone else experience this with sibo or on abx?
