Fasting and periods

I was fasting when a friend asked me how come I didn't have any lunch that day.
So I explained that I was fasting. Which lead him to think that it's Ramadhan now.
I explained no, but indeed I'm fasting to replace the fasting days I missed during Ramadhan. Because fasting the whole month in Ramadhan is obligatory, but women on period are exempted from it.

He then promptly interjected, "Oh, so you can deal with your mood swings and all the food cravings?"
I spontaneously laughed and said, yeah, we are treated very specially like that in our religion xD

And only then it was dawning on me...
yeah, we, women, do get treated very specially =')

Back then in my middle school I've always got the explanation on why women are exempted from prayers and fasting based on the notion of the impure state we have with all the menstruation blood.

But menstruation is something normal and healthy.
And I think there are much more to be learnt on the reasoning behind Islam's rules
rather than the plain stamping of women as in impure state during that period.

I think I will need to study more about this.
But I know one thing for sure, God loves me,
I'm given all the privilege to deal with all the pain, mood swings and food cravings that I have during my periods,

and i love You so very much too, my dear God, the Almighty.
