Bleeding more than normal.

I began taking the Necon 777 in November 2006 after I gave birth to my son. The first month I did fine with it but now its like I'm a totally different person. I have had a lot of mood swings toward my family and friends.I have been bleeding since Jan. 14, 2006 and still bleeding heavy today 2/3/2006. I have been feeling tired all the time even if I get 8 hours of sleep a night. Please give me some advice.
