I am currently on Microgynon 30 and have been on it for about 2 years. I haven't taken the 7 day break for about four months (holidays etc.) but in that time I had a period last month and it lasted for about nine days. Now, a month later I am having another period and it is on it's seventh day. Is this irregularity caused by not taking the pill break? Shall I finish this pack and take the 7 day break as normal?
