birth control
"I had a Mirena IUD for 5 years.  It was very uncomfortable and I would not recommend it. The removal "string" was like fishing line and jabbed into me all of the time and gave my husband abrasions. To reduce my daily discomfort, my healthcare provider cut the string short which made removal more difficult. I had a greenish weeping discharge that lasted the whole 5 years that made me think I had some kind of wound. I resented my husband the whole time I suffered this device, but I was too busy with work and kids to remember to take birth control pills.  It did prevent pregnancy and not having periods was sort of a bonus. I developed metal sensitivities during that time.  It cost about $500 to have it removed thanks to my husband's employer."
