"i got mirena six months ago and i&#039;m so happy that i did.  my doctor did not place mirena while on my period. i took a pill which softened my cervix and had it placed the next day. there was a horrible pinching feeling when she inserted it, but it immediately stopped once inserted.  i didn&#039;t bleed at all until my period started a week later... but then, i bled for three months straight.  it was mostly heavy spotting, but it was inconvenient for three months. almost to the day, three months later, i stopped bleeding and i haven&#039;t had a period since. getting mirena was one of the best decisions i&#039;ve ever made."
