I'm 26 years old, married and I have one child and have not been sexually active for over a month. Last December I was on my period for 3 weeks and it didn't seem to ease up until the last day. So now it's April and I'm having my period again for 3 weeks straight. I've noticed excessive clotting since day one and it's starting to make me concerned. What are some possible causes of this and what can be done?
