The copper (non-hormonal) IUDs are the only ones that are supposed to make periods worse, that's why im thinking of going with the hormonal one. It actually lightens the periods in 90% of women, and in 20% of women, their periods stop altogether in the first year. I made an appointment with my doctor in about a week and a half so I will talk to her and hear her feedback about all this, but the more people's opinions the better!
