I had Mirena in for 4.5 years. I had it removed December 12, 2009, had a regular period on the 16th that lasted 5 days, then 26 days later got my next period on January 10th, 2010 that lasted another 5 days. I took a pg test on day 32 and it was negative. I'm on day 37 and have yet to get my period still. I am curious if anyone else has had this issue? Before Mirena, my periods were every 25-28 days on the dot, on Mirena I only got periods every 2-3 months and they only lasted about 2-3 days. I am thinking about waiting another week and then take another pg test... Any suggestions or ideas our there?
