I have been bleeding a lot in menstruation. I started to bleed Nov 9, 2016. It lasted 4 days then it was nothing. Four days later after the 12th on Nov 17, 2016 my period came again. This time it lasted until December 20, 2016. That is 28 days of having a period. Then I stop again for two weeks. On January 1, 2017 I start my period again. I am still on it-it has been 4 days. I feel like I have been bleeding for two months. I have been pretty irregular throughout my mentruation- sometimes going a few months without a period but lately my periods are getting longer. I feel very hormonal and my emotions are unbalanced. What is happening?
