Dulcolax and cilest

I took dulcolax during my pill free week and had unprotected sex 2 days later, am I still protected? I also took them a week later 3 days after unprotected sex, but took them 3 hours after I took my pill and didnt have any bowel movements until 6/7 hours after I took my pill,but took another pill out of a spare pack later that day to be careful, what’s your opinions on protection?
