Kyleena coil and vaginal discharge

Really good contraception however I feel my breasts are sore 3 weeks out of 4.

This has been much better for me than the combined or mini pill - it has had no effect on my mood that I can tell and my periods have basically almost stopped (for the past 3 years I've had 6ish light periods a year, with 1 day of sever cramping). However, this is nothing as bad as my natural periods which normally have a week either side of just cramping. However, I have recently noticed increased breast soreness/tenderness, slight, persistent cramps and increased discharge after my last period. If this persists I'll talk to my doctor - I should be changing my coil soon away, so I'll report back :)

When first inserted 3 months ago the cramps lasted for about 2-3 weeks inconsistently and occasionally get random ones between cycles, I still get occasional spotting for 1-2 days and periods now last longer than before (originally 3-4 days, now about 4-6 days, sometimes they stop then start again over two weeks). The most frustrating thing is not being able to predict when your period will start, they are getting lighter, but I had hoped they would stop. Also a note on insertion, I know this is all recommended beforehand but make sure you take the pain killers, only local anaesthetic is applied which seemed like it made no difference. You will likely have cramps for at least two weeks or longer whilst it settles down.
