what is the difference between iud and implant?
The IUD is a small T-shaped device that goes in your uterus. Some IUDs are hormonal, and those can be effective for 3-6 years depending on what kind you get. There's also a non-hormonal IUD which can last up to 12 years. The implant is a tiny rod that goes in your arm and prevents pregnancy for up to 4 years.
