Hi
This definitely isnt normal. Mirena normally caused decreased bleeding after few months of use.Eventually there will be
amenorrhea. The first thing to do is to have an examination,to make sure that the Mirena is in the correct place. Next get an
ultrasound to check for associated caused like
adenomyosis,fibroids etc. Also get your
thyroid tested. Loosing hair so drastically isnt related to this.You should be tested for other causes with regard to that.
