That's good news, Jay!
After working on autos for almost 60 years, there are two rules I have devised for myself:
1. After doing fluid change of any kind, check for leaks.
2. After doing any kind of work at all, road check car.
These practices have saved me from having problems a number of times. Hope this experience won't deter you from DIY later. Just chalk it up to experience and watch it next time.
