I was on the Mirena for 5 years, it kept my meno symptoms away very well. Anxiety and severe depression were my latest symptoms in peri 5 years ago (never had them in my life before the late stage of peri). I am post meno now, a couple of weeks ago the Mirena was removed. I am not on HRT currently. On second night after Mirena was removed, I woke up in the middle of the night with symptoms, which I didn’t have for 5 years! Heart palpitations, not enough air to breathe and sudden anxiety. They were stopped with a small dose of progesterone. After that I had the same episode of symptoms one day during afternoon, which was easily managed with the same small dose of progesterone.
Sorry I can’t help you with advice on HRT. It didn’t work for me personally, made all things worse, so had to come out of it. My symptoms currently are easily manageable with low doses of over the counter hormonal products.
