Hormonal coil (IUS) and periods to stop

Positive - first one for 5 years, protected against pregnancy, stopped periods after about 18 months so saved money on tampons. No significant side effects initially. Set and forget method was great. Negatives - I found the fitting incredibly painful. When I had it changed after 5 years the reinsertion was traumatic and I won't have it again. I suffered with mouth ulcers every month that got progressively worse over time. My mood wasn't bad but it was overall flattened. The new one never settled and I had problems with the threads travelling upwards, I found medical staff across the board (GP, clinic, hospital for ultrasound) very uninterested when I had issues after fitting which was difficult because I was frightened of possible consequences if it moved or they couldn't get the threads to remove it. I have honestly never had thrush so much in my life as I did when I was on kyleena. Noticed more and darker body hair over time.

Not pleasant to put in but completely stopped by periods after few months. Reassuring that no pregnancy, however absolutely 0 sex drive and this effects relationships.

No periods but developed acne. I also get cysts now regularly (never had before) that burst and hurt so bad that the first time it happened I went to the ER.
