What Causes Heavy Menstrual Bleeding And Pain In The Cervix After Removal Of An IUD?

hi , i had the coil put in september, and in june, after a glass or two of wine i had the courage to take it out my self. I read through what other people had done and it did come out with no pain at all. For the past three to four months, I have been suffering from very large blood clots,pain in my cervix, fainting, put on alot more weight and light headedness. It has got to the point that i cant stand properly when i walk because it hurts so much, Even to sit down. Its making my life a misery as i have a three year old son who is very playful. HELP?s
