I have the same exact problem...For the past few months my periods have been very unexpected and lasting anywhere from 2-3 weeks. I would have my period and be on it for about 3 weeks, stop for a week and start back up again for another 3 weeks. It's completely insane and makes me worry =(
Anyways, made an appointment to see my doctor and tell him what has been going on and he gave me a chart for me to keep track of my period. On the chart I have to mark the day I started and I would have to use different symbols for the flow...such as an X for heavy an O for spotting and so on. So I would recommend starting a chart like that so you can bring it to your doctor to give him/her a better idea on how your period has been acting.
My doctor wants me to keep track of my period for a month and go back and see him to let him know how everything has been going. He had mentioned to me that what they might have to do is completely stop my period and restart it again, but that if he believes it's something more serious he might have to refer me to a women's clinic. He also had said that it could possibly be a cyst on my ovary. Bottom line is, is that you need to make an appointment with your doctor so he/she can monitor your periods to try and figure out what is going on with your body because having your period last for a month at a time is not normal...believe me I know =(
