Heavy, irregular bleeding like this for weeks after stopping Depo Provera is a known withdrawal pattern. The uterine lining builds up unevenly on this injection, and once it wears off that lining can shed in fits and starts for a few cycles. Pause MF is meant to stop the bleeding while you take it, so having it return within days of finishing the course usually means the dose or duration needs adjusting, not that something new has started.
Next Steps
Go back to the gynaecologist who prescribed Pause MF and let them know the bleeding returned despite the course, since the plan may need repeating or changing. Since this has run two months, it's worth getting a haemoglobin check done too.
Health Tips
Get checked urgently if you're soaking a pad within an hour, or feeling dizzy or very tired, since that points to blood loss needing faster treatment.
