Hormonal coil (IUS)  

Extremely painful insertion. Blood loss continuously for about 3 months, bleeding everyday. Then periods became irregular, passing clots the size of my palm. Periods worsened after merina, when ironically merina was prescribed for heavy periods. Dermatitis caused by merina after 2 months. Told that results with merina are variable, and to wait and see. Not good advice considering the health issues and extreme blood loss caused by merina so far.

First few month I havent notice any side effects at all, but after like 4 months time it does get worst day by day with all the symptoms mentioned above, especially lower back pain. I always had a pain in there before coil but it was somehow managable but now not possible even rolling on bed to another side causing me a lot of pain. Plus the endo is still growing back and having full on period, I did agree to have this coil to stopthese 2 major symptoms of my endo but the the inflamaction in my body is still high with estrogen levels sky high so there is not reason for me to keep it in,the coil definetly didnt work on my stage 4 endo and adenomyosis and will be removed today after 9 months. Hope it will help to other people everyone body works differently It does seem synthetic hormones doesnt agree with me Had the same with birth control, had to come off due heavy period while on pills and pain was still present with huge side effects. Lasted on pills 3 years.

I really struggled to come to terms with removing the copper coil as it was the best option for me after having my first child and realising how much I’d changed with hormonal contraception however, after 18 months the copper coil just didn’t agree with me causing periods that were so heavy I’d soak through the biggest tampon you could get within an hour. My periods would also last 8-10 days and be so painful, it stopped me from being able to look after my little girl properly.
