Did God create man and woman unequally?

Why is it that the physical nature of a woman is created to suffer pain (period pains, childbirth) throughout her life, when man does not? The average time a period lasts is about 5–7 days every month. Times this by 12 months and those years until menopause (average age of menopause is 51) and you get that women endure torture for a very long time! For me, i suffer pain, discomfort, stress and mood swings for 6.2 years in my lifetime!! Man does not carry this heavy burden!! And i want to know WHY!? Why isn’t man created to feel pain too? Is God really unfair when creating man and woman or are there other factors which evens out this inequality in a woman?
