Hi there, I m an 18 year old girl and I ve started to have a heavy period recently, it s been more than a week, around 9 days and I m still sort of bleeding heavily with large blot clots. I also have a fast heart beat sometimes and not very tired, but I do feel a bit tired. I haven t ever had this before, so I m sort of worried. I also have a stress factor since I am giving my final exams these days. Please let me know what the issue is, thanks!
