Prescribed Novex Ds For Heavy Bleeding During Periods. Bleeding Has

Prescribed novex ds for heavy bleeding during periods. Bleeding has been controlled. I am taking this medicine for the last two years. Now I am fifty years. For the past nine months I did not get my periods. I discontinued taking Novex ds for the past two months. I got the periods five days back with heavy bleeding and controlled with trapic medicine. Should I continue using Novex ds and I want to know the side effects of prolonged usage? How long can I use thi s medicine?
