I think IUDs are great - you simply cannot forget to take anything and they are very effective. Downsides for me are I do have a slight worry all the time around it - if it’s in the right place, am i supposed to cramp, is this normal, am i protected. I have noticed some weight gain and a bloated stomach (like period bloat that doesn’t go away). And insertion was not very nice, I had quite bad cramps for a few months afterwards. On the upside, I am much better emotionally and mentally on this after being on Rig combined pill. And I don’t have any periods - Must have saved a fortune on pads and tampons!
