"i am really worried about all of the negative side effects that everyone keeps talking about, only because i already had them before i got mirena put in. i just had mirena put in two days ago, i was on the third day of my period, and it was heavy enough for super tampons.  now, two days later, it&#039;s not even heavy enough for alight tampon, i&#039;ve been wearing a liner since i had it put in.  the process of getting it was nothing. the doctor kept telling me that i might feel a cramp.... nothing but a tiny pinch. overall it went very good for me. i went out in the waiting room for a few minutes and was reading a magazine. felt a little carsick, but that went away in less than a minute and hasn&#039;t been back since."
