Hi I am a 15 years old and my periods have been hectic for probably about the last 6 months. The cramping has become almost unbearable at time but it comes in waves, it will be a sharp pain for about 5 straight minutes(usually In my right side, but sometimes both) one of my periods was two weeks late then the next one came two weeks early, my current period is 10 days late now. One of my friends has mentioned that is could possibly be an ovarian cyst and I was just wondering if this sounded like anything anyone had went through and if so what is the step I need to take to get it treated.
