"i had the mirena inserted about 6 weeks ago.  it was quite painful, i cursed very loudly and then broke out in a sweat, but after about 10 mins i was ready to leave.  i had cramping for about 3 days afterwards but nothing major.  my first period afterwards lasted for like 10 days and i had the worse migraine ever.  the only other thing i have noticed is i have a small belly now, oh and i was so hormonal for the first couple of weeks.  

since then, everything has been good, i think you need to let you body get used to it and then all the symptoms fade.  if the belly persists, that may be annoying, but i think it&#039;s already better."
