It's possible that the people who performed your oil change failed to tighten the oil drain plug. You should take your car back to them and let them know you didn't experience this problem until after they did the oil change.
If they're honest, they'll at least look and see if it's a problem they caused.
If it turns out they were not responsible, then you need to find out exactly where the oil is leaking from before you can fix it. (And before I can offer you any advise)
