I know what you mean! I had no problems at all before giving birth. I had the Mirena put in about a month after having my son and it gave me nothing but problems (Spotting, pain during sex, etc.) I got it taken out and now I am having severe pain and I went to see my doctor today and he said that I might have endometriosis. I truly believe that the Mirena caused all of this. We want more kids but I am not sure if I can get pregnant again.

I had no problems with pain until 3 months after having the mirena inserted. I had it taken out and 2 months later I was on my knees in pain. Was taken to the hospital and found out I had a huge cyst. After 3 weeks of the cyst not dissolving I was told I needed surgery. When they did the surgery they found that I had stage 3 endo. My dr told me that there was no way possible that I would have gotten pregnant a 2 years before with this. I had the mirena put in a month after my child was born and never had any cyst or any other kind of pain. I would swear on my life that it was the mirena. Before the commercials and looking online I said it and now reading this I know.

42 year old woman that had heavy periods all my life so eventually was advised to have mirena fitted , was fully checked out under a general before. Four years later had it removed because I felt something was not right - it was removed painful due to being in wrong place - insisted on a scan - diagnosed with large 9 cm ovarian cyst . Had it removed along with ovary and they discovered I had endemetriosis which was not there before the mirena coil - this caused the cyst. I am three weeks post op and still having cramps . I also know the mirena caused this - never again.

Sounds like your uneducated endogirl. These stories are true and you are not "born" with endometriosis!

Hey everyone, so sorry to hear about all these mirena/endo complications :( My story is actually the opposite. So here's my story, I am 27yrs old, I have a 7yr old daughter after giving birth I went on the copper) paragard IUD (had it for about 6 yrs). I suffered severe pain that I would need toradol injections to ease the pain with my periods. So last year, I had hernia repair surgery, during the surgery the doctor's discovered I had endometriosis. Some of the tissue was removed during the surgery. The discovery of Endo, explained the severe pain I would have. I would have pain throughout the month, pain during sex, pain after sex, pain during ovulation, and ofcourse crippling pain during my period. I would also have long and heavy periods. After discussing my options with my Gyno, we came up with the solution of removing the paragard IUD(no hormones) and replacing it with the Mirena IUD which has hormones. So finally they removed the paragard and placed the mirena - all in one day. The procedure was pretty fast, and the only part i found painful, was the actual 2 second insertion. After the procedure I had mild cramps. Compared to my usual pain caused by Endo. I had the mirena put in about 3 weeks ago. From the day after the procedure up to today's date I have NO PAIN!!!! No pain after sex, No pain during sex, No pain during ovulation!!!!!, by now without Mirena, I would've experienced pain on a daily basis....I have not gotten my next period yet, so I dont know what type of pain, if any, I would experience. I am still spotting, but my Gyno says that that is normal for the first 3-6months. The way I see it, a little spotting is way better than putting up with heavy bleeding and pain :) Thumbs Up to the Mirena IUD...So far so good!!!! I am so much happier, especially because I dont have to endure that Endo pain. And FYI - I usually handle pain very well, so you can only imagine how severe the pain from Endo was affecting me.

I am 28 and was diagnosed with endometriosis in 2010; two years after having the Mirena IUD removed through laproscopic surgery. Why the surgery you ask? Two weeks after the IUD was inserted it punctured through my uterus. I was very nervous about all of the side effects to the Mirena so i checked for the string daily and one day they just weren't there. I went to the Dr. and had an X-ray revealing the IUD was outside the uterus and somewhere by the intestines. Because of its placement and position i needed to have emergency surgery. They were afraid it would puncture my intestines and cause further problems. So with two children and husband at home i went in for surgery. All went well and I recovered as expected. I thought that was it, all good now. WRONG! Over the next two years I had more than normal periods, with more bleeding, more pain, and lasting 2-3 days longer. Pain with intercourse was frequent and I eventually developed cysts. At one time there was a rather large chocolate cyst that needed to be removed. This meant back in for surgery. After this surgery they told me they got the cyst but had to take that ovary and tube as well because it was too damaged. Then the even worse have stage 3 endometriosis. I've been dealing ok with this now, they removed as much as safely possible but I just want everyone to know I never had any kind of reproductive issue ever. No pain, at least not more than normal, and never had endometriosis before this. So yes I do blame the Mirena IUD and wish I would have been less naive and not said, "this won't happen to me."

I am 21 and I had my IUD put in in July of 2012 and had problems pop up after. I was getting extremely bad cramps that would take me to the ground sex became unbearable and the pain made me so sick I couldn't eat anymore. Finally went to the doctor and the ultrasound showed I had 8 ovarian cysts so I was put on meds for a month and went back with little relief they then ordered a laparoscopy which showed endometriosis keep in mind I had never had an ovarian cyst before getting the mirena nor any problems in that area. I was told that it was genetic blah it's not I have no family history of this I've done my family research. I think it's odd how I've read hundreds of posts of women being diagnosed with endometriosis after having a mirena put in. And for endogirl maybe you should do your research there is ingredients in medication and lots of other products (deodorant being one) that cause something called reproductive toxicity which is a cause of endometriosis. There's a lot more to endometriosis than are in the books so like I said do your research before you tell these people they are wrong.

For those with endo...Mirena DID NOT cause it. You were probably born with it. Also medications cannot cause endometriosis. Please, for yourself and others, do some research and educate yourselves! There are plenty of books on endo. I get very tired of reading misrepresentations of endometriosis and what causes it...this is why it is not taken seriously.

I had the mirena about 4 years ago and had it in for about 4 months and started to have very bad pelvic pains, i had it taken out and 2 months later i was told that i have endo... this is very disappointing for me cuz i was on 19 at the time. my husband and i have been trying to have a baby since my iud was taken out... and still no luck.. does anyone else feel it was the mirena that caused the endo? also visit and the mirena iud is listed on there... all the symptons they talk about are symtpons of the endo...

I really wish you the best. I struggled just trying to get the diagnosis for over a year. I will someday have endo again, it's bound to happen. For now though, it seems to be at bay. I've been put on Lo Estrin 24 to help control it from coming back, if you can remember to take a pill everyday I would suggest you go that route. Mirena was great for the simplicity of not having to take something everyday, but not worth the pain everyday. If you can, it would be better to try to get pregnant sooner rather than later, if the endo gets too overwhelming for your system your chances of naturally getting pregnant will decline rapidly. Best of luck to you!
Also, I've heard there is a suit against the manufacturers of Mirena due to their not being fully honest about side effects. I'm thinking of looking into it myself.

When I had the lap surgery the Dr. removed the IUD at that time since I was coming near the five year mark. He recommended to have a new one fitted. The second Mirena I did fine with but the treatments are killing me ( not literally). I really do want to get pregnant but right now in at this time, financially isn't the best. I have read up on endo and I did find that getting pregnant is also the best option for it. I'm talking with my Dr. today about possibly removing the Mirena since this will also be my last treatment for the Lupron Depot.

I'm glad to hear that you haven't had any endo reoccurring. I'll keep you updated with what the Dr. says and how things go.

I also used Mirena and about 3 years after having it inserted had to undergo laproscopic surgery to remove the endo. I had a very rough start with the Mirena, for several months I had uncontrolled bleeding and extremely heavy periods. My doctor, (who by the way was the best!)requested I have the Mirena removed and then he do the surgery. Told me it was "textbook" and then gave me several options to treat my endo after the surgery. Including the time consuming Lupo Depron. The best option in his opinion was to try to get pregnant, which was a plan I had anyways. I became pregnant and have yet to have any issues with endo. I've been endo free for almost three years now and have a handsome little boy. I will never go back to Mirena. It was a total nightmare.

I've always had heavy bleeding until I got the mirena. I was fine for years. Then the last two and a half years of being on the Mirena, I started having extreme pelvic pain. My GYN did a laparoscopy diagnostic and come to find out I have endometriosis. Could the Mirena have caused the endometriosis? I've never had endometriosis and I'm only 27. My husband and I would like to have a kid but we don't want to try since I'm going through treatments and those treatments are a pain to deal with. I'm having severe mood swings, depression ( which I already have but has worsened ), migraines, forgetfulness, and massive weight gain, not including extreme cravings. I had the surgery in April of this year and a new Mirena put in at that time. That's when everything started to get worse. I still have some pelvic pain now that im also on a ten day estrogen tabs for when i get my monthly injection. Im worried that the Mirena caused that endometriosis and i might never be able to get pregnant.
I was having the signs of bei pregnant with feel nausious by the smell and site of food for over a week. I was tested twice and both came out negative. Please help me in finding out if the Mirena is the cause of this.
