Copper coil (IUD) and pelvic infection

I got the copper IUD after 4 years of different hormonal pills as wanted to stop being on hormones. The fitting procedure went well, the doctor was reassuring and I had local anaesthetic so it was only a little uncomfortable. However the cramps afterwards were horrific - I was on the floor in tears with how much pain I was in. Painkillers and heat pads did nothing. This lasted a couple days then thing started to settle down until the cramps turned into a stabbing pain. Returned to the doctors, they initially said my symptoms were normal then checked my vitals before diagnosing me with a pelvic infection or Pelvic Inflammatory Disease (PID). I was on 2 antibiotics for a fortnight. The pain lingered but gradually got better after a month. I have just finished my second period off the pill. My period returned after 35 days of stopping the pill which was my old usual cycle. My period isn’t any longer than it used to be but I’d say it’s a bit heavier and more painful but definitely manageable. My moods have been so much better and predictable. My skin has gotten slightly worse as expected coming off the combined pill which helped my skin, but flare ups match up to my period so I don’t mind. I got the 10 year IUD but I don’t think I’d get another due to the worry of getting another infection but I am happy with it at last.

Seriously heavy periods (wearing nightime pads and a tampon and still bleeding through my clothes in like an hour) and sometimes extruciating cramping. A lot of spotting between periods also which I've never experienced before. Nurse has told me that the coil should not affect my bleeding and I've gone straight from the mini pill to this so it may have been that the pill was improving my regular symptoms more than I realised.

I had my copper coil for the full 10 years. I had always had slightly heavier periods before my coil however after having it fitted I suffered for years with extremely heavy periods that were painful and I would leak every time. They say it doesn’t make you gain weight however I gained 5 stone whilst on it. It came time to remove it and I was going to just have another fitted however the doctor couldn’t get it out i was bleeding everywhere and in intense pain. Was sent for emergency antibiotics for PID went through a week of feeling awful on strong antibiotics just for all tests to come back negative. Spoke to dr she thinks the coil was causing these issues. Had it removed eventually (thank god!) decided against having another one! When the dr took it out, my coil that was supposed to still have a few weeks left had 0 copper left of the coil! So was completely ineffective at this point! Terrible experience!
