I have been bleeding for over two weeks now and had already had a period for a week prior to this. I am having large blood clots and am starting to get worried. I had my tubes tied with my last child 2 years ago and wonder if that causes things to change later in the body. I was also hit pretty hard in the stomach last October and noticed this heavier and longer bleeding since then. But normally it goes away after 2 weeks and starts to slow down this time it isn't and was wondering if there may be something wrong.
