Copper coil (IUD)

I used this coil as I didn’t want anything with hormones, however I started having severe pains in lower left abdomen straight after. After 18 months I had surgery to see what the issue was and I have endometriosis. I know I would have already had this, but the pains only started the month after having the coil fitted. My periods were lighter but lasted a lot longer, with pains starting 2 days before I bled. I also had about 6 cases of bad cystitis requiring antibiotics when I’d never needed them before. All of that could well just be due to the endometriosis, however, I became very depressed and suicidal at times. I believe this was a negative reaction to the copper. I now have the merina coil (3 months in) and waiting for it to settle as still having periods and I need them to stop for the endometriosis to not get worse. I’ve heard great things about the coil, but I think some people are just more intolerant to the copper, it was an awful 18 months mentally for me.
