I had the mirena put in on 11/5/2012 and It was my 6th day of the start of my period. I have read that the mirena is effective immediately if it was placed within the first 7 days of your menstrual period, but if it was placed after the first seven days you needed to use some other contraseptive for seven days and then it would be effective after that. I was wondering if that was true or not. Thanks.
