Typically, every twenty eight days, this part of a woman's cycle occurrs. You bleed, you whinge and mitch and moan that you got them, usually at the most inconvenient time and for that few days you're feeling unconfortable and icky.
Think about it this way. While your inclination to skip over the subject far out weighs the desire to address it, it is possible to think of it on a spiritual level. It is a form of release, a cleansing of sorts, where all the bad energy from that month of your life is simply washed away. On a scientific level, the uterus is relining itself and you're releasing the egg, but with that in mind, think of this.
When you release the unfertilised egg, you are letting go of the potential of bringing a child into this world, yet again, as well as letting go of the unwanted energy that your body has grown accustomed to having as a part of you. In a sense, it is a loss and becomes something you grieve over, which will result in the extremes of emotion. The result - PMS. You're cranky and everyone around you is copping it. Mix it in with bouts of sadness that you can't explain and relate this back to what you know of the grieving process, because it is possible to grieve the things you're better off without. Then when you come out the otherside of it all, you find yourself strong again and feeling in more of positive state, until the next time.
It's not such a gross thing anymore, but something really beautiful.
