Hi, I'm 20. I've always had very irregular periods, light flow, lasting 3-4 days. My periods would skip months but when I had them they were very light. For the past few months I've been having very heavy periods lasting longer then 7 days. I spot maybe once a day for 2weeks, then I have a very heavy flow for a week or so, with blood clots often through out the day. I don't have any pain in my stomach, no fatigue or weakness or cramps. It feels like I have my period for a month.
