Nondisplaced right eighth rib fracture

Use your clinical judgement. Since fully fractured ribs involve pretty severe pain, particularly deep breathing, it is possible you just have a hairline fracture, just through one side of the rib, {periosteum, cortex}, but without fracturing whole rib. Anyway, I would use pain with deep breathing, along with monitoring your heart rate , as guidelines. I hope you find this advice helpful, not a substitute for MD.
