I had the MIRENA inserted in August 08. I have 2 kids (2.5 yrs and 1 yr) The 1st 3 months I spotted A LOT and now i get very irregular periods about every 3-5 weeks I'll bleed for about 3 days. I also have a constant yellowish discharge which I thought was thrush. But after being tested for that it has come back normal. I too have tonnes of hair loss and my hair just looks dull and lifeless. I did put on some weight at the start, but have since been on Weight watchers and I've lost 15 pounds, but it's been a struggle. I've had some mood swings and been very teary, but I just put that down to some recent family heart ache (my son was diagnosed with Autism in Dec) but I guess the Mirena could be adding to my stress levels and overall wellbeing. After reading all the other posts I have booked to get my Mirena taken about next Thursday. I'm not planning another pregnancy for a few years so I need to either get organized and take the pill or use condoms.... Oh the joys of being female!
