I have an irregular menstrual cycle, my longest gap in between periods being over 6 months. I also suffer extreme breast pain. My breasts are also two different sizes (an estimate D and B cup-size). I'm only seventeen-years-old, and due to the breast pain, am struggling to play and get involved with sports and outdoor activities. I'm really self-conscious, too, and find it hard to take part in the 'normal' activities my friends get to do, like water sports. Please help!
