The two types of IUDs--hormonal and non-hormonal--differ in how long they can be used and in the ways they affect menstrual bleeding. Copper IUDs may increase menstrual bleeding and cause cramps with periods, and hormonal IUDs may reduce menstrual bleeding or stop menstruation altogether. However, women can have daily spotting for several months and it can take up to three months for there to be a 90% decrease in bleeding. Cramping can be treated with NSAIDs. More serious potential complications include expulsion (2–5%) and rarely perforation of the uterus (less than 0.7%). IUDs do not affect breastfeeding and can be inserted immediately after delivery. They may also be used immediately after an abortion.
