I to didn't have periods the whole year I was on Mirena! My question to you ladies is when to expect a period after removal? it's been a month and still nothing. I know I read on a Mirena fact spread sheet that if you don't have periods while on Mirena then it is very important to use a back up method 7 days before the removal which I only later read after it was to late . So could I be pregnant or could it just be my period is taking it's time with arrival=( Any help would be great~ Thanks!
