S.M.
I see a lot of people have had similar mild cramping - mine was so bad that I had the thing removed after a few months. I am talking cramps and bleeding just about every day for about 3 months. I had some other symptoms as well - irrational anger, paranoia and some other things that subsided after I had it removed, I am in the small percentage, I know - but if you are in that small percentage too - I wanted you to know you are not alone.
