What are the next steps for a female of reproductive age with a stable medical history experiencing vaginal bleeding with clots 3 weeks post Intrauterine Device (IUD) placement?

Vaginal Bleeding with Clots 3 Weeks Post-IUD Placement

At 3 weeks post-IUD insertion, bleeding with clots is expected and generally not harmful, but you must systematically rule out serious complications before providing reassurance.

Immediate Clinical Assessment

First, verify proper IUD placement by checking for IUD strings and exclude serious complications:

• Check for IUD strings during speculum examination to confirm the device remains properly positioned 1
• Rule out pregnancy, including ectopic pregnancy, as this is a life-threatening emergency if the IUD has failed 2
• Assess for signs of infection/PID: fever, abnormal vaginal discharge, pelvic pain, or cervical motion tenderness 2, 1
• Evaluate for IUD displacement or partial expulsion through pelvic examination and consider ultrasound if strings are not visible 2, 1
• Consider new pathologic uterine conditions such as polyps or fibroids, particularly if bleeding is severe or different from expected patterns 2, 1

Understanding Expected Bleeding Patterns

Unscheduled spotting, light bleeding, and even heavy or prolonged bleeding are common and expected during the first 3-6 months of IUD use:

• For copper IUDs: Heavy or prolonged bleeding is particularly common in the first 3-6 months and generally decreases with continued use 2
• For LNG-IUDs (Mirena, Liletta): Unscheduled spotting or light bleeding is expected for 3-6 months, with bleeding generally decreasing over time 1, 3, 4
• This bleeding is generally not harmful and does not indicate a problem if the above serious conditions are excluded 2, 3

Management Algorithm

If No Underlying Problem Is Found:

Provide reassurance and expectant management:

• Counsel the patient that bleeding irregularities at 3 weeks are normal, expected, and generally not harmful 2, 3
• Explain the timeline: bleeding typically improves over the next 3-6 months with continued use 1, 3
• Enhanced counseling about expected bleeding patterns has been shown to reduce method discontinuation 2

If Treatment Is Requested:

For copper IUD users with bothersome bleeding:

• NSAIDs (first-line): Prescribe during days of bleeding for short-term treatment (5-7 days) - options include mefenamic acid, ibuprofen, or naproxen 2
• NSAIDs have demonstrated statistically significant reductions in menstrual blood loss in copper IUD users 2

For LNG-IUD users:

• No specific medical treatments are recommended in guidelines for irregular bleeding 4
• Reassurance and time are the primary management strategies 3, 4

If Bleeding Persists and Is Unacceptable:

After excluding complications and attempting conservative management:

• Counsel on alternative contraceptive methods if bleeding continues beyond 3-6 months and the patient finds it unacceptable 2, 3
• Offer IUD removal and alternative method if the patient desires 2

Critical Red Flags Requiring Immediate Action

Instruct the patient to return promptly if she develops:

• Heavy bleeding with hemodynamic instability (potential perforation or ectopic pregnancy) 2
• Severe cramping or pelvic pain (possible expulsion, perforation, or PID) 2, 5
• Fever or abnormal vaginal discharge (possible PID, which has higher incidence in first 20 days post-insertion) 2
• Signs of pregnancy (IUD failure requiring urgent evaluation for ectopic pregnancy) 2

Common Pitfalls to Avoid

• Don't dismiss bleeding as "normal" without performing a proper assessment - always check strings and exclude serious complications first 1
• Don't remove the IUD prematurely - most bleeding resolves with time and reassurance 2, 3
• Don't forget that PID risk is highest in the first 20 days after insertion, so maintain high suspicion for infection 2
• Don't assume all IUDs behave the same - copper IUDs cause heavier bleeding while LNG-IUDs typically reduce bleeding over time 2, 3, 4
