I was the same with the mood before my period, mine too were very short and agony. Im on microgynon 30ED and the pain is practically gone!! And the moods are fine --i even got taken off of my antidepressants! There is a blood clot warning, saying, of 100,000 women who are not on the pill, about 5 will have a blood clot in a year... then of 100,000 on a pill like the microgynon,about 15 will have a blood clot in a year. It does say if you're in a wheelchair it may increase the risk, but that to speak to your Dr who could try find an alternative. Jess xx
