Hi, may I answer your health queries right now ? I am 44 years old. I was previously on Mirena and after the 5 yr. limit, had another one inserted. Since then, I have experienced significant weight gain, my hair has been falling out, and my migraine headaches have gotten worse. Is it safe to be on Mirena if I am experiencing pre/perimenopause or could the IUD be contributing to my worsening symptoms?
