Hormonal coil (IUS) and heavier periods

I had such high hopes for the Mirena to help with my heavy periods but sadly I'm nearing the six month mark and there has been no improvement in the long term, if anything my periods are worse and I can't find any reason online as to why. I couldn't put up with the monthly flooding any longer and the NHS waiting list was at least 12 months, so I paid privately for the Mirena to be fitted. The insertion was uncomfortable but bearable (I haven't had children) and I didn't experience any discomfort immediately afterwards. The cramps during menstruation in the first two months following the fitting were intense, but the period was lighter so it still seemed like a win overall and I remained hopeful the cramps would ease as my body got used to the coil. That has happened and the cramps have eased to next to nothing now, but strangely my periods after the three month mark have been horrendous. I've been losing clots bigger than I have experienced before and I am back in incontinence pads to manage the amount of blood I lose. I can't continue to afford to access private care and I remain on the NHS waiting list, where I guess I will discuss ablation when I finally reach the top of the list. I so wish this had worked for me because it seemed an easy option and importantly it didn't end my fertility, but sadly it wasn't to be. I don't know why I'm surprised it didn't work for me, this is just my luck!! I wish it hadn't cost me hundreds of pounds to find this out, but for those it works for it seems life changing so it very much felt like an avenue worth exploring.

I tried the Kyleena coil for nearly 6 months. I previously tried a wide variety of contraception methods but nothing agreed with me. This was the worst one. Even during my sixth month of having it, the pain was like nothing I've experienced before. Very painful during sex. Hot flushes frequently. Heavy bleeding for the majority of the time I had the coil. Awful cramps. Constantly tired to the point I was napping on breaks at work. I'd sleep for 13 hours at a time and still feel tired. The only positive was that my mood didn't seem to change.

I am 15 years old I have been on countless contraceptives I have just come of the depo shot to go on the ius coil and it was a easy procedure there is a downside thought I have had cramps that only seem to be getting worse and the bleeding has gone from light to heavy this is the first day of having bad bleeding but I don't really know what to think I went to the doctors and the string were still in place and everything was fine and now the bleeding had become worse I have done all my research but I still don't know whether this is normal I have a constant fear of the ius being expelled or displaced and I am just really worried I know it has only been 1 month but I'll just have to see if it improves
