Front lower than the back

I drove out to go for a meal and my car was fine, no issues over speed bumps at all. On my way back I noticed the car wasn't driving quite the same and noticed it more when I got to the speed bumps where my car was grinding over the bumps. When I got home I found my front end was very close to the ground, which was not like it before. What could this be? Not long had the car so I am taking it back to the garage to get it sorted.
