Help...charcocaps???

I had the stomach flu and took charcocaps (activates charcoal to help with diarrhea). It says that it’s supposed to bind to the toxins and help take them out of your body. However, I took the right dose 12 hours ago and I have not had to go to the bathroom since. My mom says they’re supposed to be constipating but I’m not sure? Feel like I have to go but can’t now.
