Patient's Query
Hello doctor,
My 28-year-old daughter had a Mirena IUD inserted four months ago for heavy periods, but she is now experiencing many problems. She had severe cramping and bleeding for the first six weeks after insertion, which her gynecologist said was normal. However, she is still having constant pelvic pain, and her periods are actually heavier than they were before getting the IUD.
She went back to the doctor, who did an ultrasound and confirmed that the IUD is in the correct position, but she is still miserable. The strings feel shorter than they did initially, and she is worried it might be moving or perforating her uterus.
She has also developed acne all over her face and back, something she never experienced, even as a teenager. Her mood has been volatile, with anxiety and depression that began shortly after the IUD was inserted. She tried taking Ibuprofen for the pelvic pain, but it only provided temporary relief.
Her gynecologist wants to wait another two months to see if the symptoms improve, but my daughter wants the IUD removed immediately. She is also concerned about getting pregnant right away if it is taken out, as she does not want to go on hormonal birth control pills either.
Are these normal side effects of the Mirena IUD, or could they be signs that something is wrong? Should she get a second opinion before having it removed?
Please help.
Thank you.
Hello,
Welcome to icliniq.com.
I understand your concern.
So four months in with Mirena (T-shaped, levonorgestrel-releasing intrauterine system) and she is still having constant pelvic pain, heavier bleeding, mood changes, and acne, which is not the usual pattern. The first six to 12 weeks of cramping or irregular bleeding are common, but by three to four months, most women start to see lighter flow and less pain, not worsening.
If she feels the strings shorter, that raises concern that the IUD (intrauterine device) might have shifted deeper or partially embedded, even if the ultrasound says the correct position. Acne and mood swings can happen with Levonorgestrel (the hormone in Mirena), but if it is this severe and she is miserable, forcing her to wait longer may not be the best option.
Based on what you’re experiencing, the symptoms can be explained by a few Mirena-related factors. The hormone levonorgestrel can sometimes cause side effects like acne and mood changes. Ongoing pelvic pain may be due to a mild inflammatory response, and the shorter strings raise the possibility that the IUD may be sitting higher than ideal or partially embedded. Heavy bleeding can also occur if the device is not positioned properly within the endometrium.
To understand this better, a repeat pelvic ultrasound is useful, preferably a 3D scan or saline infusion study to assess for embedment. A pelvic examination can directly check the string length and position. If bleeding has been heavy, a complete blood count should be done to rule out anemia. Hormonal tests are usually not required unless acne or seborrhea is severe and not improving.
While Mirena-related causes are most likely, other conditions are also considered, such as pelvic infection (less likely in the absence of fever or discharge), adenomyosis or fibroids causing heavy periods independent of the IUD, or mood symptoms overlapping with underlying anxiety or depression.
The most likely explanation is either malposition of the Mirena or hormone-related side effects from the device. If you wish to have it removed, that is completely reasonable. No one should continue with an IUD if it is worsening symptoms or affecting quality of life. Removal is quick, done as an outpatient procedure, and fertility usually returns immediately. If you do not want hormonal pills afterward, options include a copper IUD, condoms or other barrier methods, or non-contraceptive treatment for heavy periods, such as tranexamic acid during menses.
Acne often improves after removal, though some cases may still need dermatology care. If you choose to keep it for another two months, strict follow-up and a repeat scan are important, but given your symptoms, early removal is a valid choice.
I would like to know whether your ultrasound specifically mentioned embedment or only stated “position normal,” and whether any pelvic infection screening was done. If blood loss feels excessive, hemoglobin should be checked. If you decide on removal, you can proceed now and use condoms or a copper IUD as backup. Please update after removal or repeat imaging so further guidance can be given.
For the future, detailed counseling before insertion about hormonal versus non-hormonal IUDs is important. Mood should be monitored closely with any hormonal contraceptive, and regular pelvic follow-up is advised, typically at six weeks after insertion and again at three months.
I hope this helps.
Please follow up if you have any further concerns.
Thank you.
