I had mirena and want fond of it, my Dr warned me either your cervix will love it or hate it (weird way of phrasing it lol) and mine hated it. sex was painful :( my husband's friend's wife had it and it traveled through her uterine wall and attached itself to her abdomen. I now have nexplanon and I like it a lot. only issue is when the hormone started to run out the first time I had it my hormones were imbalanced and I turned into a psycho lol
