Any bad points?

• A lot of women have slight but irregular bleeding for the first six months
• Temporary side effects can include headaches, acne and breast tenderness
• Some women develop cysts on their ovaries. These are not dangerous but can sometimes cause pain. They usually disappear without treatment.
• Can be pushed out by the womb or become dislodged
• Can puncture or perforate the womb which may require removal by surgery, although this is rare
• Doesn't protect against STIs, including HIV/AIDS
• Small chance of infection after the device has been put in.

Where can I get one?
