Welcome to the forum!

It's nearly impossible without being able to inspect the vehicle to determine what the leak is and how critical it is. If you're really concerned about it, pay the $20 or so to have a professional check it out.

It could be something as simple as puddled oil in a frame rail or similar from the oil filter change, or it could be a leaking or loose drain plug. Additionally, it could be completely coincidental that the leak started so soon after an oil change.

Maybe you've had the leak for awhile, but this shop used the correct oil viscosity for your engine and previous changes used a heavier oil which didn't leak as readily.
