Hormonal coil (IUS) and lighter periods

Had it inserted at birth during a c section so no pain for insertion. Periods for lighter every month with significantly less pain than before and have virtually stopped after 8 months - just a small amount of spotting.

I've had the mirena coil for four months, I'm still bleeding irregularly (period every 8 days) and lots of spotting. I've been dizzy for months, I'm feeling very low, I have water retention and a lot of lower back pain that feels like a pinched nerve so I'm battling to concentrate on work. I really want to have it removed but I'm terrified of going back to the alternative of extreme heavy periods that made me anemic.

I had Kyleena for 5 years. For the first 6 months I had painful cramps, but my cycle became very light. I have noticed that I have had increasingly more acne, especially back acne, so be prepared for your skin to be very itchy. Towards the end of having it, I had constant light bleeding through the month and there was no regularity to it (probably because the hormones were wearing off). I have had incredibly bad bloating, water retention, and generic weight gain. I'm a very light build so this weight would normally have been easy to lose. Finally, I had to undergo investigations for ovarian cysts as I was getting all the symptoms for them, and after a bit of research it turns out that Kyleena can be a contributor to the formation of cysts. Overall, I have really liked the Kyleena. The side effects have been fairly insignificant compared to other methods. But just take into account the potential insidious side effects like cysts etc that can happen. I've now switched over to the copper IUD because of these side effects, and I'd prefer to be hormone free.
