Ouch! Poor you!
I have no idea what the answer to your question is, but I took a hard fall on gravel a year ago, hitting hard on my left ribcage. I didn't even notice the rib area at first, worrying more about the scrapes on my thigh and shoulder, but over a few days, a small area of my ribcage got really sore, and it hurt to breathe in, laugh, press on it, and cough. I did a little online research and determined that it was most likely I'd just bruised a rib or two, since it gradually got better over a period of a couple of weeks. Cracked ribs take longer to heal, as I understand it, without an x-ray, you may only be able to judge after the fact whether, in fact, you cracked or only bruised a rib.
Perhaps someone here who has cracked ribs before could chime in -- unfortunately I know there are several here who have been there, done that!
Hope you heal up fast!
