If there was no nasal bleed immediately and has occurred twice and that both the time in the morning while blowing the nose. This does not seem to be serious. Only thing I would advise not to blow your nose for few days and that the blood will stop by its own. Watch for severe headache
, watery discharge from nose( rhinorea), blurring of vision and weakness of one side of hand or leg. If any of these occur report immediately to casualty.
Thanks and be careful.
