In April 2016 I Had Abnormal Bleeding And Visited A

In april 2016 I had abnormal bleeding and visited a Gyn. My uterus scan showed a thick endometrium 22 mm , so was adviced a D & C . The histopathology report showed that I had Complex Hyperlasia without Atypia - endometrium. i was adviced hysteroctomy but i took a 2nd opinion and my Dr. adviced to start me on hormone tabelets Meprate 10 mg 3 times a day. I am still taking but now dosage increased to 50mg per day. past 2 scans showed my endometrium come down to 4mm and last week scan showed it to be 3.71mm, good improvement
But i am bleeding/spotting continuously and from last week i had heavy bleeding so i am confused if my treatment is going in the right direction???
