IT could be from many things. Most commonly is the drain plug is loose or the gasket on it is bad. However, it could be any of the following:
oil pan gasket
valve cover gasket
rear main seal
What I would recommend is taking it to where you have your oil changed and let them recheck their work to make sure everything is tight. Also, while the vehicle is on the rack, if they tell you it's not leaking from where they worked on it, ask them if they can see where it is coming from and to show you. Let me know what you find out and I will explaine what needs done. NOTE: Make sure the oil is full. Based on your description, it sounds minor.
