Stopped bleeding on HRT, what does this mean?

Age 41, have premature ovarian insufficiency at 36, started HRT 7 months ago, was bleeding every month, noticed last 3 months less flow and this month no period. I’m taking 2 pumps Estrogel and cycling 200 mg utrogestan. What does this mean? I wonder if I need more estrogen? Please comment what you think this might be 🙏🏻
