You need evaluation of your nose
Your nose will need evaluation to answer your question. If any bones are broken or you have internal injury to your nose you will need treatment.
Trauma to the nose from a softball injury
Anytime there is trauma to the nose, it's important to visit an ENT facial plastic surgeon to determine whether not the external nasal bones have been broken, the septum internally has been broken, or the upper lateral cartilages have been dislocated off of the nasal bones. It's also important to get x-rays to document any potential nasal fracture.

Bump after injury
Hard to tell without examination. If there is a bump, it most likely a displaced cartel, and or bone.You will have to wait several weeks at this point to allow swelling to decrease and for potential surgery to re-align the structures that may be damaged.
Since you were just injured yesterday, you will need to give your nose time for swelling to dissipate. It usually takes several weeks, and in some circumstances, months, before all temporary effects of trauma have resolved. I would consult with an experienced rhinoplasty surgeon in your area who can follow your progress. Good luck!
It is very difficult to tell at this point. The nose gets very swollen when it is injured and just from your description, no one would be able to give you a 'yes or no' answer. I would recommend visiting with a local rhinoplasty surgeon so they can assess in person.
Best of luck
Likely soft tissue swelling
Without an obvious deviation of your nasal bones, it is likely the softball caused a soft tissue injury, called a contusion. A contusion will normally settle by 10 days after the injury. If you are concerned you have fractured your nasal bones, you should arrange to see an ENT Specialist within the next 10 days.
I hope this helps!
