以下的英文 文法有冇錯 ??

I didn't feel well this morning because I was sick.
My father was sick, too.
The exam were coming and I didn't wanna miss every opportunity of study.
(So I went to school as normal.)
(However,) I ask for an early leave for the first time in the whole school life of my Secondary school.
I have a slight fever in this morning so I went to see a doctor.
I thought I can go to school today.
Oh, there were an English oral, a Putonghua oral and a Science dictation today but I had missed.

我估內容應該係咁, 希望冇會錯意。
