You are on a sequential form of HRT so you will continue to have a bleed each time you finish a progesterone course. It's not a real period, it's a lining clearance and has to happen to keep your womb lining thin. You won't know if your natural periods have stopped because of this forced bleed. You will always bleed whilst taking HRT this way. Depending on your age you could ask to try continuous HRT. You could use the same products but just take 100 Utrogestan every day. Talk to your doctor about it if you are fed up of the bleed and you are OK on the progesterone part of the course.
