That sounds awful. I had a copper IUD before we decided to have a kid, and I hated it. I'm on the depo shot now. It's been 6 months and I hardly ever get a period anymore (just when I'm super stressed out, it seems). The first 3 months were really rough, but things have evened out. Still have some side effects, but I'm mostly on it to control my PMDD which it is, so it's a trade-off I'm willing to accept.
