I Have Recently Started Having Trouble Emptying My Colon And

I have recently started having trouble emptying my colon and after a bowl movement will have small amounts that seep out throughout the day. My bowl movement has become lose and kind of a sticky consistency. I recently started taking a probiotic once daily. Could that be the issue? Going on vacation this week and would like to have firm bowl movements and not have to deal with this. Eating more fruits and vegetables lately as well.
