birth control
"I would not recommend for anyone. What the doctors fail to mention is the constant pain and discomfort. They will also make excuses when asked to have it removed telling you to wait. 
After 5 years of pain, no sex life as the cramping is not worth it. finally i was granted my wish to have it removed. Unfortunately it was surgically as it had went into my uterine wall. The doctors fail to mention this product can ruin lives as im not sure if i can have children. Threads were still visible and had regular checks too. 
3 days it has been gone and my headaces, cramps, pain down my leg gone with it.
Yes it stops pregnancy but at the cost of it being potentally permanent and also the lack of sex drive.
My advice please avoid."
