I also suffer from extreme mood swings with my cycle. I went on the pill when I was 14 (as my cycle was also very irregular) and it helped me immensly. Now I am 27 and I decided to go off the pill as I plan to have a baby in 12 months or so. In the first week after stopping the pill I was crying uncontrollably. I started taking a PMT herbal formula and within a week my mood was back to normal. I still have mood swings but they are nothing compared to when I am not taking the pill or PMT formula. If you are concerned about your daughter being too young to take the pill, look into getting a PMT formula that has evening primrose in it. I have found that because it also has vitamin B12 and other vitamins I also feel a lot healthier physically. Best of luck with your daughter. It would be good to sort it out when she is still young - you don't want her to spend her teanage years in this condition. Shan
