Any vaginal bleeding after menopause with a coil (IUD) fitted should be assessed promptly by a clinician, even if it is light, pink, or a one-off, because it is never considered normal once you have gone 12 months without a period. A hormonal coil such as Mirena can cause irregular spotting, especially in the first months after insertion or near its expiry date, but other causes must be ruled out first, including vaginal or endometrial atrophy, polyps, fibroids, infection, and in a small number of cases endometrial or cervical cancer; expect questions about your coil type and fitting date, a pelvic exam, and often a transvaginal ultrasound or endometrial biopsy, and do not try to remove the coil yourself. There are several important factors that change how urgently you should be seen and what testing you need, so see below to understand more before deciding what to do.
Because postmenopausal bleeding has both harmless and serious explanations that look identical at home, a few minutes spent organizing your symptoms can help you ask for the right assessment sooner. Take a free, instant, online symptom check to better understand what may be driving your bleeding and to plan your next steps with more confidence.

Bleeding After Menopause When Had Coil Fitted: What to Do
Bleeding in menopause when had coil fitted can feel alarming. By definition, any vaginal bleeding after 12 months without a period is “post-menopausal bleeding” (PMB) and should always be evaluated. If you have a coil (intrauterine device, IUD) in place—whether hormonal (e.g., Mirena) or non-hormonal (copper)—and notice new bleeding, it’s important to understand why it may be happening, what tests are typically done, and when to seek urgent care.
Key point: Even if bleeding is light or infrequent, always let your doctor know.
Hormonal coil (levonorgestrel IUD)
– Typically thins the endometrium further, often leading to lighter or absent periods in pre-menopausal women.
– In menopause, breakthrough spotting or light bleeding in the first few months after fitting may occur, but persistent bleeding is not expected.
Copper coil (non-hormonal IUD)
– Doesn’t alter hormone levels; may cause heavier or longer bleeding in menstruating women.
– In menopause, any bleeding is abnormal and needs assessment.
Bleeding in menopause when had coil fitted can arise from several relatively harmless issues. These include:
Seek medical attention—ideally within a week—if you experience:
In these situations, call your GP urgently or attend your local urgent care.
Keep a bleeding diary
– Note dates, flow (light, moderate, heavy), clot size and any associated pain.
– Record any discharge, fever or changes in your general health.
Check your coil strings
– Gently feel for the threads at your cervix’s opening. If you cannot find them or feel the plastic device itself, the coil may have moved.
Avoid vaginal tampons, douching or intercourse
– These can introduce infection or irritate the lining further.
Use sanitary pads
– Pads allow you to monitor blood loss more accurately than tampons.
Your GP or gynaecologist will want to:
Take a full history
– Onset, duration, amount of bleeding, associated symptoms.
– Date of menopause, type and date of coil insertion.
Perform a pelvic exam
– Check for visible lesions on the cervix or vagina.
– Assess coil string position.
Arrange imaging
– Transvaginal ultrasound to measure endometrial thickness and confirm coil position.
– If the endometrium is thicker than 4–5 mm, or if polyps are suspected, further tests follow.
Recommend endometrial sampling
– A biopsy (pipelle) of the uterine lining rules out hyperplasia or cancer.
– Often done in an outpatient setting with minimal discomfort.
Test for infection
– If you have symptoms such as fever or discharge, swabs may be taken to rule out endometritis.
Depending on the cause, management may include:
Although the overall risk of cancer is low, timely investigation is vital. Endometrial cancer is highly treatable when caught early.
Not sure whether your bleeding warrants an urgent visit? You might consider a free, online symptom check, using the doctor approved Ubie Symptom Checker. It can guide you on next steps based on your specific symptoms.
Final reminder: While many causes of bleeding after menopause when had coil fitted are benign, some can be serious. If you experience any worrying symptoms—or if your bleeding is heavy or accompanied by pain, fever or faintness—speak to a doctor without delay. Your health and peace of mind matter.
