One user shared that they have the Kyleena IUD and it changed their life. They experienced severe pain during placement, but after the IUD was inserted, they bled for less than 10 days in the past 2 years and their endometriosis pain reduced by 80%. Another user mentioned that the Mirena coil worked wonders for them, reducing the frequency of their periods to every 2-3 months and making them lighter and less painful. However, some users had negative experiences, with one mentioning nonstop bleeding for 3 months and another experiencing daily cramping pain. One user also reported that their small uterus size caused additional abdominal pain due to irritation from the IUD.
