hello and welcome to HCM,
Our nose is one of the most bleed susceptible organ in the body. Even a small trauma can cause injury
and bleed. But the same is in the case of healing also as it has so much blood supply that it heals pretty well and fast!
Having said the above, we know that your nose bleed will eventually stop and also it will become better but it is always better to know that there is no crack in the bone or cartilage
or just a tear in the skin which may require a stitch.
In any case consult an ENT who may do an endoscopy
to rule out any active bleed or injury and perform an X Ray
for a bone fracture
. Like you asked even cartilage may break and bleed but it is not a major problem
If the shape of the nose has changed much and you have nose block the doctor may also suggest more definitive measures
Meanwhile do not blow your nose hard and do not meddle
