I had an awful experience with mirena coil my side effects were:
panic attacks
anxiety
headaches
sore breasts
depression
crying
dizziness all day
fuzzy head
feeling dazed
the list goes on, but i had mine removed 10 days ago and all the above have disappeared thank god! i would not recommend this to anyone, please liste to your own body, i waited 7 months to see if it would get better but it only got worse. The nurses/dr's still think mirena has no side effects but the 100's of women on websites like these seem to prove otherwise!
