E.O.
Hi Cinthia,
I had the Mirena inserted in Feb; i too had longer periods that lasted about 2 to 3 weeks in length (heavy the first two months, now seem like they are a bit lighter and it is the spotting that lasts). From what my ob/gyn has told me, and a few friends that also have Mirena, my periods should lighten a lot, and then eventually stop by the time it's been in for a year). Everything you mentioned seems normal from what I've experience and heard.
