"i got the mirena inserted about 4 days ago on the first day of my period. since i&#039;m 19 i got it for free at a teen clinic! i experienced bad cramping with insertion because i have not had a child, but it was nothing i haven&#039;t felt before. i have a heavy menstrual flow so i bled and cramped a lot the first three days, but now it&#039;s day 5 and i am not even spotting at all. obviously it&#039;s soon to tell if i&#039;ll have other symptoms or irregular bleeding but so far the process has been a breeze for me and i love my mirena!"
