If bleeding persists after 3 months, reassess to evaluate bleeding pattern, as recommended by Praxis Medical Insights 1
If bleeding continues and is bothersome, consider adding low-dose estrogen if medically eligible, using NSAIDs for short-term treatment, or switching to a sequential regimen, as stated in Praxis Medical Insights 1
