I'm 18 with no children and planning on getting an iud, what are the odds of my iud being expelled? and is it true the pain will be much worse for me?

Minimal: The literature suggests the spontaneous expulsion rate for iud's is about 2% to 3%. The copper "t" iud is approved for women regardless of parity. The insertion procedure can cause some cramping, pain, and spotting - however, significant pain or discomfort during the procedure is uncommon. The benefit of the iud is that you get the most effective reversible contrception currently available.

Low chance: The iud is rarely expelled and is it a very good method of birth control if you want to delay childbearing for a few years. There is a small amount if cramping associated with insertion that goes away quickly. I usually recommend that a patient takes 2 Ibuprofen an hour or two before to help prevent the cramping. Your doctor will teach you to check for the strings to verify that it is not expelled.
