My name is belle. I am 13. I have been getting my period since July, 2013. I never gave much thought to how long my period was, just WHEN it started. Then I heard that anything over seven days is bad. Well, I am almost positive that all of my periods so far have been between 6-10 days starting at minor bleeding or spotting to spotting/no need for liner. I am on the tenth day of my period right now, and although I am only using a liner, I am very scared that something very wrong is happening to me. I am crying right now and very worried. Please help! Other info about me: weight:102pounds, height:5' 4", I am very active, mainly in dance. I am on a competitive dance team as well. I do not remember blood clots, maybe a few, but smaller than my pinky finger nail and rare. Thank you.
