Hello there
I have been longing to contribute to this thread, but the admins have only just approved me. I had the Mirena fitted on 16th May, a couple of weeks before you Nas, and I am having it removed on Wednesday!
I have a history of terrible PMS prior to having my children, so the Mirena was recommended as the gold standard for me. My main perimenopausal symptoms have been depression and anxiety which were solved by being on a 100mcg evorel patch and doing two weeks of vaginal Utrogestan. As the Mirena was supposed to be the most convenient way of keeping the womb lining thin and has very 'low systemic effects' I booked myself in for a fitting. Literally the next day I was completely flat and the day after I cried all day which I don't think I have ever done before. Then I continued to feel very flat, depressed, tearful, occasionally OK and intermittent terrible brain lethargy. I saw a private menopause specialist and she said stick with it for three months, but after reading all the stories on mums net and elsewhere on the internet I decided that I'm not going to risk it never getting better. I also thought that the progesterone component was a body identical progesterone like Utrogestan but actually it's the same synthetic progestin that is in the pill I took in my twenties which took away my libido and probably contributed to depression and pms. Clearly the Mirena works brilliantly for most people but the psychiatric side effects are well known and listed on the leaflet that comes with it and if you've had a history of pms then you are more likely to be one of the unlucky ones who finds it a struggle. I will let you know if I notice any changes when I have it removed.
Thanks for reading and good luck to you!
