WELCOME TO HCM!
you are having short duration low grade fever
which can be due to viral infection or due to some inflammations as in your case as you said there is bleeding from your nasal septum
so may be there is an abscess which is causing fever.
MY ADVICE is to visit an ENT specialist
and get yourself examined.
some basic tests like CBC,Urine examination,Smear for malaria
should be done if fever continues.
I sincerely hope this will help you!
