I used to have a difficult period. In my teens it would come upon me unannounced at 38 days or 43 days, whenever my uterus decided to get busy. By my early twenties, things had pretty much settled down and my period had become just another small nuisance to be taken care of. Most important was making sure that I was prepared for it. Not being prepared for it on one occasion had led to my crowning moment of street attitude, followed shortly by my crowning moment of street humiliation.
