"i had my mirena inserted 10 weeks postpartum and it has been wonderful! i felt mild cramping during insertion but i haven&#039;t felt a thing since. i took an ibuprofen before hand just in case it was going to be bothersome. my husband says he can not feel the string. i have not had a period (it has been 4 months), but i am also still breastfeeding. i love not having to remember to take the pill. i highly recommend. there were no crazy side effects here."
