"i&#039;m 20 years of age and got a copper coil 4 months ago. instantly, i had problems with it. during the 4 months i would bleed constantly for 2 weeks with only a 2 week break in between. with my recent period i became very ill. i was bleeding extremely heavily, getting dizzy and vomiting. once at the doctors, they removed the coil straight away and informed me that i had an infection caused by the coil. i was warned that my body may reject it, however i was not warned that i could get an infection due to this. as stated i am 20 and did not expect to hear that the infection could have caused me to be infertile if not detected as quickly as it was. it may work for others, but i had a pretty bad experience with it."
