I had the Mirena inserted over a year ago. When my ob inserted it, he cut my cervix. I suppose that should have been my first warning that this was going to be a nightmare. I have since been miserable. I have had headaches, nausea, dizziness, weight gain, swelling so bad I cant ever wear my wedding rings. I bled for the first six weeks and haven't had a period since, this seems unnatural to me. My weight fluctuates so badly i have to keep three different pant sizes in my closet-due to water retention. one day i'm a size 10 the next a 14. I have gained 15 permanent pounds. And my eating habits haven't changed a bit. I weigh more right now than i did the day i delivered my THIRD child. I am also on antidepressants, which started 8 weeks after the mirena. I am having it removed tomorrow. my husband had a vasectomy so i wouldn't have to deal with this anymore. If you are looking before insertion. . . . .RUN. . . RUN SCREAMING. The mirena is an awful form of birth control. I wish I had never had it inserted.
