Could any one please help me to corect my letter which i already drafted below , As i am abigginer on learning English i don't know whether it is good or no.
this what i wrote:

I would hereby request from you to approve grant me one day as a sick leave on every month this will be only duringmy pregnancy period. As the doctor at Al Mangaf clinic has prescribed me monthly check up so I have to be absentduring this day because it will take time to complete.
I hope for your kind consideration." I would be much grateful if you grant my request"Thanking you,

Also i want to Know is it better to say "I would hereby request from you to approve grant me one day as a sick leave "or
" I would like to request from you to permit me one day as a sick leave"
