Bleeding Patterns and Management with Levonorgestrel IUDs

Understanding Bleeding Patterns

Unscheduled spotting or light bleeding is expected primarily during the first 3-6 months of LNG-IUD use and typically decreases with continued use 1
Over time, bleeding generally decreases with LNG-IUD use, with many women experiencing only light menstrual bleeding or amenorrhea 1
Heavy or prolonged bleeding, either unscheduled or menstrual, is uncommon during LNG-IUD use 1
Approximately half of LNG-IUD users experience amenorrhea or oligomenorrhea by 2 years of use 1

When spotting occurs after a period of stable bleeding patterns, consider IUD displacement, STD or PID, pregnancy, or new pathologic uterine conditions, and check for the presence of IUD strings 2
Evaluate for signs of infection 1
Rule out pregnancy, especially if bleeding pattern has changed abruptly 1
Consider polyps or fibroids that may have developed 1
Check for IUD strings to confirm proper placement 2
Evaluate for signs of infection or other gynecological issues 1
Treat the condition or refer for care if an underlying gynecological problem is found 1
Provide reassurance that bleeding irregularities are generally not harmful if no underlying problem is identified 1
Counsel on alternative contraceptive methods if bleeding persists and is unacceptable to the patient 1
Offer another method if desired 1

Don't remove the IUD without first investigating potential underlying causes of spotting 1
New-onset spotting after a period of stable bleeding warrants evaluation 1
Don't automatically attribute spotting to the IUD "wearing off" when other causes are more likely 1
Ensure proper counseling about expected bleeding patterns to improve continuation rates 1
