different bowels

Hi Iam a 30 year old female. I recently started taking benfiber a few months ago to add more fiber as well as eat more fiber. I was taking the minimal amount of benefiber (1tblsp) and had to stop because I felt I had to run to the bathroom a lot. It's been over a month since I've stopped taking it and I have a lot of gas whne I go to the bathroom and my stoools are a lot loser. I have no pain at all and feel great. I still eat the same, a lot of veggies, low carb, and some protein. I am just curious as to why my bowels are loser since I have stopped taking the benefiber. Did I cause a spasm in my bowels or something?
