"pros: 
didn&#039;t get pregnant

cons: 
had to go on the combined pill anyway to stop a constant heavy and extremely painful period.
period between packs of the pill was even heavier and more painful. took over a week of taking the pill again to make it stop. 
awful mood swings. 
pain at the insertion site
once it&#039;s in, the nhs will be very reluctant to remove it if you have problems
botched insertion made removal even more difficult difficult when i had to be hospitalised due to the blood loss
bottom line: don&#039;t do it"
