Could I have possibly broken or fractured a rib?

The other day, i had a softball game and i had to dive to a base (due to my knee, i'm not allowed to slide) so i dove to the base head first. I hit my stomach off the Ground, but felt no pain at the time. Nor did I hear any cracking or anything. That was 4 or 5 days ago. Now I just realized the pain, and it's on the right side. Its not my upper ribs, it's my lower ribs, closest to my hip. I noticed the pain because i've been having bad stomach pain lately, so I went to feel around my stomach and I could feel one of the ribs on my right side almost shift, and then it hurt afterwords. And as far as breathing in goes, I don't feel a pain while i breathe in, but after i breathe in I do. Like say I was wearing a sports bra, i feel the pain about an inch or so underneath the sports bra. What do you think I did? I'm not saying me diving into second base was the cause of this, but it seems like the most logical thing. Oh, and whenever I run Alto, i start to get a bad cough. What did I do, and can I continue to play softball (because I have one More game left adn it's the championship).I'm so sorry for writing a novel, and I thank everybody who takes the time to read all of this.
