"i had mirena inserted at 10 weeks postpartum.  there was a little cramping but i&#039;ve had worse cramping during my period than having this inserted.  i have 2 kids and had c-sections with both.  only ever got to 4 cm with the first one so they did a repeat c-section w/ the second. i love it. i don&#039;t have to think about birth control and i&#039;ve had it for 4 months now and no problems.  i&#039;ve recommended it to all my friends."
