Hit something under the car on awful road

Arnold

So I had to go to a wedding in the countryside, and didn't expect having to drive through a terrible cobblestone road, shaped like this ^. I was obviously very careful and drove super slow but at some point I hit something quite hard, I could "feel" it from the inside of the car.

I stopped, had a look and I can see a mark on the engine protection. Car is still driving well, it's been 1,5 days now. However, after it happened I saw something leak. It was definitely not oil though. I assumed it was just some water from an earlier puddle but I want to check with you guys if you think I should go get it checked anyway?

This is a pic from the under of a 350, but here's where it seemed to leak. It doesn't anymore.


Thanks!
