Hello J.,
I have had Mirena for for 3 1/2 years now, and absolutely LOVE it! I have already made plans to have it taken out and put a new one in at my next OBGYN visit. I do have a friend who had one fall out, and had another put back in. It happens occasionally, Expulsion is listed as a possible side effect on the Mirena website. The friend who had Mirena come out has had no problems with the second one, and it has been in for over 2 years now. I would probably request that the Doctor actually put the Mirena in this time not the PA, I am not saying it is the PA's fault, but they don't have the same amount of school as an MD and the IUD has to be placed in the exact right place in the uterus. So since the first one fell out I would insist that the OBGYN put the new one in. I really think it is the best thing out there as far as birth control, there are no horrible side effects like with the Depo shot where your hair falls out, you really don't have to think about it other than check the strings occasionally, you didn't pull the strings did you? The strings are to make sure that it is in place properly you should be able to just barely feel them but the doctor pulls them to remove Mirena, I warned my Husband about this one about a million times. It also has if you ask me some wonderful side effects, like I haven't had a period for almost 4 years, and my friend who has it, hasn't had one since she has had the second one put in, not to mention she got it because she had her first daughter planned and got pregnant with the second while taking birth control pills, and she says she did not forget to take any, she was totally surprised. So Mirena seemed like the best choice, and it really has the lowest risk of side effects of any form of birth control. If you go to the website you can find out more information and they have the patient information packet available to read that has all the side effects listed. Here is the website www.Mirena-US.com good luck with everything hope it works out for you.
