birth control
"At the start of taking the levonorgestrel  I thought that it was great. No side effects.  At week 3 I started my period, which I was kinda expecting because of the warning of break through bleeding. The period was the worst I had ever had, a lot of bleeding and tissue loss. I consulted my doctor and she kept telling me that as long as it was getting lighter there was nothing to worry about. On day 25 of  I was hospitalized and needed an emergency blood transfusion.  They gave me 7 units of blood. I would say NEVER take this BC pill."
