"-the mirena iud insertion was about an 8/10 on pain scale. after i left the procedure, i had zero pain that night and wasn&#039;t limited in any way. in the weeks following i had minor cramping. i had my period for about two straight months following insertion. 
-i had my mirena inserted in march, and it is now mid-july. i get my period at least once month, sometimes with heavy cramping on day 1.  
-my biggest word of caution is regarding weight gain. post insertion i&#039;ve had a lot of issues maintaining my weight and i am truly consistent with what i eat. i&#039;ve gained 10 pounds w/o changing my diet. it is very hard to the lose weight. i&#039;m now 3 mo.  post insertion and my weight has suddenly levelled back out, with no changes to my diet. super weird."
